 Posted: Sat Jun 02, 2012 9:06 pm Post subject: Two issues |
 |
|
| Jacked up both sides of the car today in attempt to find the cause of my sb wobble, and found two potential issues. First the drivers side wheel wobbled a little bit when I shook it. (bad bearings maybe?) and when I spun the passenger side wheel, I heard a slight rubbing noise for about half of the wheel rotation.. Any ideas on what the problems may be? |

What way did you move the wheel back and forth? 12 o'clock and 6 o'clock or 3 o'clock and 9 o'clock? You probably have a bad bearing or one that needs adjustment. Take off your hub cap and grease cap, tighten the jam nut and see if the play is gone. With the other wheel.. take the drum off and you'll probably find something in there.. can't tell ya without looking at it. Start inspecting!

i ask what end of car..???
i rattled around in your posted photos is this the 73SB? not van.
this car has struts in front. (McPherson.)
front or rear?, there are 4 wheels. 5 counting spare
the bentleys book, amazing as it is , has this data. and METHOD.
(is not an answer) the correct answer
is
I moved pressed hand inward at the tire at 6 or 12
the other 6 and 12 is the ball joint test, lifting. (there 2 tests) which 1.?
so if press test? then you see play , and if the backing plate
of the brakes dont move then that is wheel bearing play
if the brake backing plate moves that is JOINT play.
easy peasy just look at the parts, they are all connected.
the wheel bearings have .001 to .005 inches play.
this is normal, and at the end of the lever this play is amplified
by the rules of Archimedes.
more. play at edge of tire. this is NORMAL.
you can tell this is the bearing play , how come, because
the brake backing plate does not move. so it must be the bearings.
then comes the other parts.
depends on what end, I Assume front.
the ball joints. if SP the strut too.
the tie rods.
the track rod. holding bottom of strut (A arm, if you will)
use a lever and discover what is loose by application of force
and see what moves and by how much
each amount is covered in the book, and varies by year.
The tests in my book shows. How to test each part.
1 by one, and the method.
there are lots of tests.
I used a dial indicator on mine, but one ball joint was at .25 inches.
and in that case , .040" is a NO GO, just look moment. no gage.
there is also normal steering wheel play in its gear box.
the tie rods should have none. (they move but no play)
one keeps an open mind,does all the tests. and finds what 40 years of abuse exists.....
now if the play is not excess wheel bearings
but is in the STrut
what do you do next
that is easy, look at it. while you lever or force the tire.
does the strut move at the top or bottom.
if yes, its bad.
but what is bad.
if the top moves the mount can be bad,or the inside of the strut cartridge
is mangled.
if the bottom moves.
it might be loose but look again at what moves.
is the A arm flexing. when you tell us what is moving and what is not
the answer happen fast.

DO NOT JUST TIGHTEN THE JAM NUT!!! a wheel bearing failure at freeway speed can cost you your life..adjust it correctly according to the bentley manual.

it's amazing who so few ever learned how to adjust bearings.
there are many kinds
guessing is a death experience. ever loose a wheel at speed..
or almost die from someone elses?
$30 book , less than door mats and you save a life one time.
and $30 well spent. why fear books, ?
if the bottom ball joint fails and falls apart. tell me what happens next
at speed.
and once they wear , the wear rate increases, due to increased velocity
of that movement. bang bang , harder and harder each time.
tell us what moves and what don't. and live.
if you frear dial gauges? then you can do the Rob& dave washer tickle test
or my angle test (i dont, but here it is)
for the lazy.
see my angles (math)
the first choke line is zero play (exactly)
the next is .003 play (mid spec)
clear huh? see write up with photo its all there.
if you think all this is bs. you too can go to Timken bearings.
and see the stress tests on there bearings
they set them too tight
then too loose ,then plot the data curves for failure ,
they fail in 1000s miles or less, catastrophically.
a bell curve.
VW just specs them in the sweet spot. only you can believe it.

Johnny, this is what I meant. I told him to do a test to see if the play was gone if he tightened it. This would mean his bearing needed to be adjusted. If the problem was not corrected, a bearing would be needed.

Thanks for the info fellas. To answer a couple of your questions, It is the 73 super beetle, it is the front end, and on the drivers side I pushed in and out on the drivers side tire at 12 o'clock and that is where I noticed the slight movement and sound... didn't happen at 3 and 9... Passenger side wheel didn't move or make noise when trying to move it around at 3 and 9 or 6 and 12... only makes the rubbing noise when I spin the tire..
Since I just moved back to Sacramento and am staying in the hotel still, I guess I should just try to find someone here in town who knows what they are doing and is willing to look at it for me. Unfortunately I don't have the tools or the know how to fix it right now. I look under the car and don't really know what I am looking at. |
