Rear wheel bearings
Hey all
Just wanted to know who runs unsealed wheel bearings on a lowered beetle. I was wondering if you were to use 'stock' unsealed, bearings, would they
be starved of oil due to the negative camber of the rear wheels?
On a similar note, who uses sealed bearings? Do they seem to last?
Thanks!

good point they should be unsealed on the rear axle to allow the oil flow to the balls
if you do happen to buy seal type the plates can be flicked out pretty easy with a screw driver
when replacing them you should re face the bearing retainer to make it flat wet n dry on a glass plate
this will help with sealing and stoping oil leaks from a distorted retainer face

Hey Dave
Wouldn't it be ok with the grease inside the sealed bearing? Or don't they suit this application?
Reason I'm asking is that I'm getting a roaring noise which is quite evident at 70--80kph.. and I can feel a high frequency vibration though my
steering wheel. The front bearings are fine as I repacked them a couple weeks ago..

there is not enough grease in a bearing to last as a rear wheel bearing...
When using ball bearings, I pop out a seal, and fill with lithium based Moly grease... and put the seal back in place...
did You use lithium based Moly grease in the front wheel bearings?
blackish-bluish grease...
what's recommended by Volkswagen..
if the grease was green... its clay based grease..
I only use it on My tappet cover gaskets....
never in bearings..
Negative camber..!! Just make sure You fill Your gearbox up
so there is enough oil to do the job...
I haven't heard of anyone having problems with negative camber and oil to the bearings..
naturally, they weren't like that from the factory..

did You check that the bearings were OK
before refilling with grease?
if they were pitted or badly worn
grease may help, but that's not fixing the problem by the sound of it..
I would think if You can feel it thru Your steering wheel
it would eb the front wheel bearings..??

No they really should have the oil circulating not grease, if you do have grease then the oil will eventually wash it out every time you go round a
corner and the oil surges

I think the question was. Does the transmission oil get to the bearings in a lowered rear end when the axle tubes are rising up toward the wheels?

Hi
Do you have a roof rack on the car, they can make horrible noises.

OK so vibs through the wheel
Check all the front end tie rods King n lings for wear wheel bearing tightness Good bearings
Wheel nut / bolt / lug tightness DONT over tighten
I dont think vibs at the front will transmit from the rear are yr front wheels balance correctly
that will keep u going 4 a while

yes depending on how many corners you go around the oil will slosh out
