1302 wobbles
I have heard that the M/Strut front end beetles get a wobble up, Mine gets one about 80kph and gets quite violent, i have adjusted the slack out of
the steering box to about 25mm free play at the outside of the wheel, struts arent leaking , wheel bearings have been done. any help appreciated
Cheers
RJ

After the above,80kph is the critical wheel balance speed,also check steering damper and fit a strut brace.

Mine does it at 55km/h, quite specifically. It's fine below about 53km/h and the wobble goes away at about 58km/h. I feel quite happy with that,
whereas if the wobble was at 60km/h I would be extremely angry!

joel always suggests just moving the front wheels 90 deg, or one bolt to the left/right... not a permanant fix though i dont think..

Hi
I've had supers since 1973, I battled the dreaded shimmy for years, fitted new steering boxes, universal steering joints, lower ball joints, tie rods
& steering dampers.
All these things helped but the most useful things to stop it were Urethane bushes in everything and skinny struts with heavier front springs, I
personally believe that the front springs are too light which causes most of the problems.

Steve there's always one to give you a headache, I have a client with a super cab, with 4 stud chromies, strut brace and all good nick suspension
joints and urethane bushes.....it's constantly on the verge of shimmy if you have uneven road surface....I am wondering about lifting the rear as it
has the saggy rear torsions look and way in the air in the front, so maybe caster has quite an effect ???

Hi Mat
I had heaps of problems when I was running 14 inch 7 & 8 inch Magnum eliminators (OK it was the 70s), I had to get an on car balance or have the
shimmies.
When I went to 15 inch wheels, then 16s & 17s it seemed to go away.
When I had the shimmies bad, I found a quick flick of the steering wheel would get rid of it.
Even my sons bug with stock wheels, skinny V Force struts and Urethane bushes had no shimmy, for a short period of time it had a loose lower ball
joint no shimmy, now with 17 inch wheels its a steady as rock. It has a worn steering damper bush in the pitman arm now, still no shimmy.

I have found that simply having the wheels balanced on the car was mysolution many years ago.

I dropped 35kg in the spare wheel well this afternoon and I have managed to shift the wobbble start point to 60 - 65 kph checked all the bushes and
ball joints, they seem OK have organised new ones any way, will fit on weekend and booked in for an alignment and balance Monday, will keep you
posted

If your wheels' contact patch is out board of the point on the ground
where the imaginary kingpin axis intersects, it will aggrivate the problem.
This is common on aftermarket wheels.
Added caster can help, as can better steering damper, but it is probaby a bandaid.

I had this problem. The bushes, ball joints etc were fine. A new steering damper was an instant cure.

those plastic ones always fall apart
a 72 probably should have had the metal sleeve though.
re. the shimmys what wheels are you running?
with nearly all the supers I've owned 90% of the time if the balljoints and bushings are even half decent its the rims that cause it
small diameter seems to amplify the problem but the worst are all those dreadfull 70s ROH wheels like hotwires, globes, hurricanes etc with the square
shank bolts that dont center properly but stock steelies with small buckles/wobbles seem to bring it on too
as mustard said above I;ve found moving the 1 wheel at a time 90 degrees on the bolts can sometimes atleast dampen it if not cure but only if all the
rest is good

Running 5" chrome mangles I think they are called.
Seems todays effort, alignment and balance has got rid of them for now.

thats an Lbug you have there so its after 73 which is why its got the disintegrating plastic steering shaft sleeve instead of the metal one, more cost
cutting on vw's part
Sometimes the offset of those wider rims can upset the shimmys by widening the track

Hi
I had the same problem, I just cut plastic sleeve and fitted it in the gap. If you cant find the correct size plastic sheet I have a heap of it, I can
send you a bit in the mail.
