Mine is an 88 4WD S10 Blazer, 2.8L.
Serious rumble/rattle/clunk in the rear appears to be the passenger side axle
has too much slop in it, at least relative to what I would expect to find, and
also more than the driver's side. Hard to measure, but perhaps it moves in an
out about 1/8 inch. Either way, it seems excessive and seems to cause the noise
when rolling down the street.
I am not that well versed in the differential, so I am wondering how to take up
this slack. Can the axle be shimmed at the clamp where it is held to the pinion
gear? Can't think of anything else that might fix this, so any advice or
suggestions would be much appreciated.
Thank you all for your time and consideration.
