Pardon my lack of proper terminology, I will try to explain the best I can. the axle that goes into the diff has way too much travel when you tug on the wheel at 12 and 6 which makes me think it's my problem. What makes me think that there is a problem is on occasion when I am taking off and making a right turn you can hear and feel a popping. I have checked everything else, half shaft u joints are solid so I dont think that is it. I am not good at all with suspensions (have done a little with jeeps), and the back end of a C3 Vette really intimidates me. I have also read threads where guys have a heck of a time getting the half shaft off at the hub so I'd really like a pro to tackle this job. Murphy of Murphys law has something against me so I'm sure if I attempt it what can go wrong will!!!
I do appreciate the offer of assistance though :thumbsup3:
if I understand you correctly, its the axle/spindle bearings that are worn and loose?.. yeah, if you have no mechanical skill at all, its probably best to let a pro handle it, they need to be set up with proper clearence after reinstall...however,worn bearings usually make noise [ sounds kinda like rolling a handful of marbles back and forth in your hand ] in a straight line as well.. the noise on turning, could be just a lack of Friction Modifier in the differential itself, causing the posi-trac to chatter when turning at low speed.. .a differential gear oil change and a $7 bottle of F/M will clear it up...
Thanks fish, I do have some wrench turning skills, do my engine work and such but as I said I am not comfortable with the back end of a Vette, if I had helped or done one before I would probably be up to it but have read too many threads about guys having difficulties with getting 36 year old bolts to come lose, I just don't have the expertise or tools to deal with that.
I would think if it was a lack of friction modifier, and that would be great if it was, then it would do it all the time. Yesterday I took it for a ride, not a peep out of it!
I believe it's where the axle goes into the diff, there is quite a bit of play there, more so than on the other side and I'm willing to bet that the diff has never been apart, the odometer is showing (when it last worked - I just picked this up in September), 102K on the clock.
alot of times the posi won t chatter cold, it only does it hot, its worth a few bucks in oil and additive to eliminate it.. probably needs an oil change anyway.... but, not hearing the noise myself, its hard to tell you exactly whats causing it.... the bearings should make noise turning or not...especially at crawl speed.. sorry I can t recomend anyone out there..I ve heard good things about Corvettes of Houston, but thats pretty far too.... just holler if we can be of assistance
