Re: Loose rear spindle nuts on C2
Just some thoughts from the many arms I rebuilt. It is not all that uncommon to find large mistakes made to arms by vette shops, garages, and dealerships. The experience and job skills of the mechanic are more important then where the job is done. One question I have is with your terms, runout refers to rotor runout through 360* of rotation. A loose spindle nut will not have much effect on runout but it will on bearing endplay which I believe is what you are referring to. I have seen "rebuilt" arms come to me with no shims just the spacers, others reuse the same shims and press them together- not good. If you are using disc brakes you want the bearing end play set to 0015-002" and rotor runout under 003". If you are using drum brakes there is no runout to be concerned with but the endplay should still be checked. The concern I have is you found poor work, so how good is the rest of the work? If it were mine I would be breaking them down to do them right. It's better to install new USA Timkens now while they are still made here then to risk a bearing failure later. Just my opinion.
