Sorry to cry wolf but I thought I'd get more views this way
My 87 GN has a bad rearend problem. When I finally got to pull it out of the garage(first time I ever drove it) it was acting strange, kind of wobbly feeling. The best I can describe it is an erratic jolting in the drivetrain. It feels like the rear end is binding up but it is making no noises. I put it on jack stands and put it in gear. I had the wheels and hubs off and noticed a very slight wobble in he axle. It seemed to be really smooth at that point. I took the axle to a local machine shop and the closest he could tell me was 12 thousandth of on the outer casing of the bearing, he referred me elsewhere because they really didn't know what was good or bad on an axle. I called an axle shop today and they said they couldn't accurately check it.
It is a Ford 9" rear end with 31 spline Moser axles. Even if one of the axles was ever so slightly bent, would it cause that noticeable of a problem at such slow speed?? I'm wondering if the axle is the problem but figured it was my first thing to check.
I'm thinking it may be the wheels but it seems like it wouldn't be erratic but more of an every revolution feeling. The wheels are DragLites that have the funky double layer metal where the lug nuts go through with a metal spacer in between. Maybe the lug nuts are a hair too long and not completely tightening the wheel to the drum.
Anyhow, I have both axles ready to have checked but need to know what to look up in the Yellow Pages. Any ideas?? Any other possibilities for these symptoms?
Thanks!!
