Lowered Beetle
landfall - June 9th, 2014 at 03:46 PM

OK, thanks to the thread by Joel I managed to identify and purchase a 1976 Std Beetle.

Now this particular car has been dressed up like Herbie.

It has also been lowered using the spindle method, so I gather it is 2 1/" lower?

There is about 1 inch of clearance above the tyres on the front.

The ride is terrible, I have ben in go-karts with better suspension. It feels like there is no suspension movement and it is virtually riding on the bump stops.

It appears to have plain shockers with no over riding springs.

I would like to raise it 25-40mm, not possible if I return to standard spindles.

I could live with the height, but currently not the ride.

Any suggestions, please.

Ken

If you replace the spindles with the standard spindles it will still ride the way it is now, it needs no over ride springs as the torsion bars carry all the weight, how can you tell it is riding on the bump stops as these are inside the shock absorber with a plastic cover over them, there could be other issues with the front end like worn trailing arm bushes, seized ball joints or incorrect shocks that do not allow full movement of the suspension, a vw factory manual is a good investment http://www.ebay.com.au/itm/BENTLEY-WORKSHOP-REPAIR-MANUAL-VW-BEETLE-KARMANN-G... ,it will give you all the information when you need it.

Thanks vwo60,

I am new to the world of older VW Beetles and therefore appreciative of any help.

AS I said, "it feels that it is virtually riding on the bump stops, I have a feeling that it will be the incorrect shocks. Planning to jack it up tomorrow and have a decent look.

The other indication that it sitting on the stops is that when pressing downward on the front guards, there is no suspension movement.

I have already ordered the VW workshop manual off EBay as you have suggested.

I definitely know there are other issues, it wanders all over the road at any speed and there is a lot of play in the steering.

Going to be an interesting time coming my way.

Thanks for your reply.

Just a suggestion, not a wise move normally, remove the front shocks and take it fore a short drive around the block, this will give you a indication if the shocks are the culprit, it probably will be time to overhaul the front end, be aware of after market things like ball joints and steering boxes, a good second hand German steering box is better that a crap new one, your one might adjust up just fine, will you be doing the work yourself, German ball joints are available for a bit extra, a four wheel alignment is worth the effort when you have finished what ever work on the suspension the car requires. all good fun and seeing you are a vw virgin probably a step learning curve, the car is simple and most repairs can be carried out your self. that what I think this hobby is about.


landfall - June 9th, 2014 at 08:34 PM

Thanks for the tips.

Have been surfing the net for various products.

What's your take on GAZ adjustable front shockers, the type suitable for the lowered suspension of course, vs the KYB brand?

At this point in time, I am seriously considering replacing most or all of the wearing components, such as ball joints, sway bar kit, steering damper arm, etc.

Totally agree with your sentiments about this "hobby." That is what I purchased this vehicle for.

Before you start looking parts you need to deceide what you intend to do with the car, part of your problem with the front could be that the shocks are to stiff for the car, hence you cannot push the front down and it rides like a dray, if you were to keep the car standard then you would use a low pressure gas shock or a good quality oil shock, when you want to change the wheels and suspension to improve handling then a high pressure gas shock could be used but along with this comes a harder ride, a compromise can be reached, I have run a lot of shocks over the years but now all my cars are fitted with KYB gasajust and they all ride very well, you will hear exactly the opposite from other people on the forum. works for me. rebuild your suspension and add the other parts one at a time so you can see if there is a improvement that you are looking for, if you keep the dropped spindles you will need a standard length shock, the dropped spindles are the best way to lower the front, if you lower it by installing adjusters without the dropped spindles using the standard height spindles the lower you go the worse it rides. that is a characteristic of the suspension.


landfall - June 10th, 2014 at 06:51 AM

Thanks again for the advice.

Although I am about to measure the shocker length, I would have thought that I would be needing the "lowered shockers" but you have said keep the standard shockers.

The car will basically only be used for club outings. I should point out that we are both in our seventies, so I am not looking for a hotrod. We were looking for a standard car, but here in Tasmania any beetle is thin on the ground and those we did look at were shocking. This one was by far and away the best one we looked at, but has been played with. Wish they had spent as much on the ride and handling as they had on the stereo and amplifiers:lol::lol::lol:


vwo60 - June 10th, 2014 at 07:15 AM

If the car is fitted with dropped spindles the front will be lower by 2 1/2" with the suspension at it normal position, thus the standard length shocks, lower the car with weld in adjusters and drop the front the same amount you will probably benefit from shorter shocks, but then you can bottom out the ball joints and you will have the atrocious ride you do not want. A good book to get your head around the suspension, http://www.ebay.com.au/itm/How-to-Modify-Volkswagen-Beetle-Chassis-Suspension... When you jack the car up check if the car has dropped spindles, on standard spindles the centre line of the stub axel is directly between the ball joints, dropped spindles are 2 1/2" higher up towards the top ball joint. also look to see if weld in adjusters have been fitted to the beam, they will be welded into the centre of the upper and lower torsion tube and have a adjusting screw to preload the torsion bars. just need to find out what has been done to the car and its condition. get a few posts up then you can upload photos.


landfall - June 10th, 2014 at 08:41 AM

Thanks again. I plan on jacking it up later today.

First thing today is to take it up the road and get quotes to take out the two rear quarter windows and the rear window and fit new rubbers.

Should I move this thread to tech talk?


Bizarre - June 10th, 2014 at 08:58 AM

G'day

leave your thread here as most people click "Topic Activity" and you get all the posts since the last time you visited

Otherwise maybe start a new thread

Shouldn't cost much to get the windows changed over unless you want new rubbers with the chrome in them
Can be a bugger to fit


landfall - June 10th, 2014 at 09:11 AM

Yes, that's the ones I would like.

The front windows have been replaced with this type and would like to match them.

Ken


landfall - June 10th, 2014 at 12:38 PM

OK, a bit more information.

I have stripped the front wheels and measured the distance between the top ball joint and the lower, 150mm. Therefore the centre of the axle should be 75mm? It is offset by 15mm upwards. In other words the distance from the top ball joint to the centre line is 60mm?

Does this mean that it has standard spindles as they certainly not offset 2 1/2".

The beam seems to have an adjustable device in the centre of each beam, but they do not look like they were welded in place. Looks a part of the beam?

If they are height adjusters, which way do I turn them to vary the height?

The shockers are shot. This I think is the route of my problems. The ball joints, etc look in good nick.

Ken


vwo60 - June 10th, 2014 at 05:42 PM

This should help you determine what you have, In the middle of the beam on the standard front end it has two grub screws and a lock nuts, this hold the torsion bars in place, check out the video to see the adjusters. http://www.youtube.com/watch?v=1ciOjDeKZrY 


Deadpan - June 10th, 2014 at 06:15 PM

Hope you sort out you Bug Ken if you want more manuals and VW books cheaper than Ebay -example- BENTLEY WORKSHOP REPAIR MANUAL VW BEETLE KARMANN GHIA -Ebay $74.95 + $6.95 Standard Postage = $81.90 -Nile books $57.49 with FREE shipping! http://www.thenile.com.au/search?s=Volkswagen+&x=33&y=21 


landfall - June 10th, 2014 at 06:38 PM

OK, vwo60 thanks for the diagram.

I do have the standard front beam, grub screws and locking nut.

The bump stops on the shockers are totally destroyed. The shockers are a Brazilian brand "cofap" and the shockers measure 340 depressed with no bumpstop and 440mm extended.

The same measurements apply with the car sitting on the ground without the shockers and when jacked up the suspension drops to 440mm.

Other than the slight offset on the hubs, I cannot see how it could have been lowered so much?

From a bit of research I find that these measurements are standard size shockers. The shockers for lowered cars seem to be too small.

Ken

Thanks for the tip on the bookshop Deadpan, looks like I will be spending a dollar or two with them.


vwo60 - June 10th, 2014 at 07:46 PM

You might find the torsion bars have been cut, did you drive with out the shocks to see if it rides any better, post some photos of the ride height so we can see it.


landfall - June 10th, 2014 at 08:12 PM

OK, will do tomorrow, thanks for your help.

Ken


landfall - June 11th, 2014 at 03:51 PM

OK, managed to take the measurements.

I trust they will make some sense.

The distance between the shocker mounts with the car jacked up (no weight) is 430mm.

With the car on the ground= 310mm

The same distance with the shockers in place = 440mm and 330mm.

The ground clearance from the bottom of the running board on a level surface is 165mm.

The bump stops on the shockers were destroyed. I cut away the bottom part that was damaged and left a small cushion of rubber that was still intact. This gave me a measured movement of 25mm on the downward stroke of the shocker.

On the road, this did make a difference to the ride, not fantastic, it still bottomed out, but much better.

The stroke of the shockers are 260>440, I think that this is the range of a standard shocker and should be OK.

Will try again to attach photos separately.

Ken


landfall - June 11th, 2014 at 03:57 PM

The other two photos.

Spindle and modified shocker.


MrSpeedy - June 11th, 2014 at 04:43 PM

Take a pic of the centre of your beam, under the nose of the car where the centre grub screws are. Top and bottom tube.


landfall - June 11th, 2014 at 04:48 PM

OK, will do that tomorrow.

Looks very standard to me, no weds etc.

Ken


vwo60 - June 11th, 2014 at 07:41 PM

If there are no adjusters then the torsion bars have been cut or they have sagged with use, It indicates to me that it is a lot lower than stock with the standard car always higher at the front compared to the back, if you are going to change at least the ball joint boots you can remove the trailing arms and the torsion bars and check it out, there are torsion bars available that are 10% stiffer, it works very well in the front and I have these in two of my cars, the sway bar bushes are RS, you can get a uprated front bar also, no dropped spindles, do the wheels rub at all, if you fit them it will increase the track 6MM a side, my be enough to make the tyres rub. it is important to maintain wheel travel if you want the car to handle, when you lower them without the dropped spindles you will get a crap ride, as you have found out, the design of the suspension requires the trailing arms to be at least parallel or angled down a few degrees to get the ride. when you go lower the front you loose this and the wheel now has to move up and forward into the bump rather up and back away from the bump. keep up the good work. Did you check the you tube video I posted showing the adjusters.


landfall - June 11th, 2014 at 08:06 PM

Yes I did check out the utube. That is why I know that it has not been lowered using that type of adjusters.

The tyres rub on full lock on rare occasions.

Where are the stiffer torsion bars available and does replacing them entail pulling the beam out?

Waiting for the manuals to arrive, but trying to get on with the job.


vwo60 - June 11th, 2014 at 08:27 PM

It will entails the removal of the trailing arm, then the torsion bars. I bought my bars from CB performance in the States
http://www.cbperformance.com/ProductDetails.asp?ProductCode=6297 
This way you can check out the condition of the trailing arm bearings


landfall - June 11th, 2014 at 09:03 PM

Thanks.

A little work ahead, plus a new exhaust system.

Ken


landfall - June 12th, 2014 at 03:45 PM

vwo60,

The mob in the states do not have the HD torsion bars at the moment.

I have managed to take some slack out of the front end, adjust the steering box, reassemble and take for a run.

It's livable, just. More like a 1949 MGTC than a bug.

At present getting prices for new sway bar and shockers, plus an exhaust system (badly needed).

Tried classic vee dub, but their phone is always engaged or out of order and they do not reply to emails?
