Noise/ vibration from front *solved (wheel brg)*

DLP · Post by **DLP** » Thu Jun 26, 2008 8:02 am

I have a vabration that you can feel from the stearing wheel and the seat. I thought it was an unbalenced tire. So I had them rebalenced and even rotated. It made no difference. I think it is comming from the passenger front area. I put the truck up on jack stands and had my boy shift in and out of reverse and drive to test the u-joints. I replaced the u-joints a couple months ago and thought one of them might be bad. All looks good there. Going down the road the vibration climbs steady with speed. I ran the truck in OD, D, 2, 1 and N. RPMs didn't change anything. The vibration is consistent with tire speed. Could it be a worn front axel CV joint? I know I had to replace them pretty often on my 87 S10. Thanks for any help. Darrell

brake rotor?

Possibly a wheel hub starting to go, that vibration was one of the first things I noticed in mine.

I had the same experience with a mini-van I own a few months back. Yes, it was the front cv axle. I replaced both with remans from Autozone and the problem was gone. Most reasonable priced place I could find at the time for a reman axle shaft. Cheaper than trying to fix the old one and lifetime guarantee too. On mine I could get up to 40+ mph and it would be shaking pretty badly. If I let up on the gas it would "recenter" itself and not shake until I hit a bad bump or slowed down or stopped. Given that the front diff isn't always pulling on our CC's I would say you are on the right track. BTW no visible external damage was apparent on my shakey axles either.

Front Wheel Bearings Diagnosis

DLP · Post by **DLP** » Fri Jun 27, 2008 4:04 am

Thanks for the replys. I couldn't find/see any physical trouble with the CV. But that dont mean there isn't any. I did the front brakes last fall. Turned the rotors too. The wheel bearing sounds like a place to start. Any advice on checking any of these myself?

You can follow the link in the post above and see the official test method or you can do what I did, jack up the car and spin the wheel, in my case I could feel the bad spot as a rough spot when it turned, also pull and push the wheel any movement in and out is not permissible and will tell you the bearing is bad.

Sorry. I missed the link above. Thanks to all. I did jack the front end up. Then using a second jack, lifted the arm and wheel up even. I did get a little play. But I thought it was just warm ball joints. I will do it again tomorrow and pay better attiention! I will also follow the link above. Thank you, Darrell

Just wanted to thank everyone and closed this thread as repaired! I replaced the hub/bearing yesterday. That was the problem. I was all set to have to pop the ball joints, pull the stearing and have it re-alined. What a relief it was to pull the brakes, 3 hub bolts and the axel nut. Took me about an hour and a half. I bought the hub at the local AutoZone for $130. I ordered a second one off line for $65 shipped. Figured I would replace them both to be safe. I have a trip comming up this weekend and didn't want to waite for shipping. I think I should be able to do the second one in about a half hour. Thanks again for the help. Darrell

Glad you got it fixed. I'd put antisieze on the second bearing assembly's mating surfaces. Not on the fastener threads, though. It will make the next go around really quick.

Thanks for taking the time to share the solution. Many times the question gets feedback and we never hear what solved the problem.
Thanks.

Glad we could help, it's about time for me to offer a solution instead of creating a new question. Sorry it had to be a bit of an expensive fix but it would have been worse if you had just started randomly replacing parts.
