While changing the right rear wheel bearing, the 36mm spindle nut wasn't even tight. That sent a chill up my spine. I mean sure it has a keeper with a cotter pin that won't let the nut completely come off but I'm sure you get going fast enough it would'nt matter. I'm curious to see if the drivers side rear is the same way. So there may have been nothing wrong with the wheel bearings at all. Oh well its getting new ones now. So for anybody who thinks they've got a vibration do to bad wheel bearings check your wheel spindle nuts first. It may be as simple as that. Not everything that goes wrong with these cars is complicated.

Hmmm, interesting. I'll add that to the list of things I need to check on my '90 Z.

If it had the cotter pin was still installed it seems to me like someone didn't tighten it correctly.

rhipsher · 01-30-2010

Not only that but on the same right rear one of the lug nuts was pulverized/cross threaded. I can thank NTB for that. Before they put the vreds on 1 1/2 years they were fine. I mean what do I have to do? Buy my own tire mounting machine to because they can't do that right either. And when I had my exhaust welded on those damn rednecks scratched my 49th streets rocker panal.
Anyway that's probably why that tire had unusual wear on the inside and probaby caused traction problems at the strip. When there is only 1/4 of your tire is making contact with the ground that will cost you dearly.

Well after putting everything back together and taking it fo a spin I am happy to report the vibration is still there. hehehe. Oh well I had nothing better to do today but waist money on parts I didn't need and waste my day working on something that didn't solve anything. Back to the drawing board. I hate suspension issues.

Hey Rick,

is it possible that the loose spindle nut caused the tire to get scalloped, do you think it's possible? I'm thinking that if the tread got scalloped, the scallops could cause it to vibrate? What about the lug stud holes on the wheel, could they be ovaled out due to the loose spindle nut? I know I'm shooting in the dark here!

I hear you about some of those "tire technicians"....I had to stop one going after my lug nut covers with an impact gun once. I would have paid money to have seen the expression on my face! Of course, later that yr I got a flat and found that they had cross threaded three lugs on my right rear. I feel for you.

Well I tend to try and just take my wheels in and have the tires done If I can get away with it.

Unreal that some Fuk can't instal a tire without crossthreading the lugs stupid kids with a impact gun

I agree but I don't have a truck. And when you stack two 315's on eachother they are so wide that I can't even close the trunk. I miss having a truck. Forget the Bmw/merc or next vette. I'm getting a truck.

I had to have two new tires put on the rear(the one & only time I've had to deal with a tire shop). I called ahead to ask if they could do the job. I took the wheels off the car, marked with chalk on the tire where the sensors were, and gave them a paper with the name/site location of GM Parts direct & part numbers of the sensors so they could immediatley order new ones if they broke them. I couldn't imagine putting an impact wrench to them.
Never-the-less, they did put a mark, on one of the wheels; small but I can say I'll try a different place next time. Why is it so hard?
