'89 Iroc with an apparent bad ring and pinion in the rear diff according to previous owner. my question is is this something worth trying to fix this or should I just replace it with a spare rear end?

Anyone have a 10 bolt for sale or know a local shop that rebuilds them for a reasonable price? every shop ive called wants over a grand. I messaged Dyno Don a few days ago but no response yet.

Your 89 is equiped with a 9 bolt rear if its disc brakes.

Drum brakes

Is it a throttle body injection? That would be drum brakes. Or a 305 TPI automatic would have drum brakes and 2.73 gears, too.

If you want to upgrade to disc brakes and better gears, a whole rear end swap would be your best bet.

It's TPI. 2.73 rear drum posi..

I do not plan to keep the car long.. so keeping costs to a minimum is ideal. The most efficient way to do it would be to find an exact replacement.. just don't know how realistic that will be.

Getting a "new" rear from a salvage yard will likely be your cheapest solution. Typically a car isn't scrapped because the rear went out... so it should be useable.

Otherwise, buy new gears ($200), bearings, gaskets, misc parts ($200), and labor to install ($200-$300) makes for a $600-$700 ballpark. YMMV.

if your gonna get rid of the car, look on your local craiglist or shop around. should be able to find a used one very cheap.

have you pulled the cover to see whats exactly wrong with your current rear?

Pulling a complete rear out of another car will be your best bet drum rears out here in cali can be had for under 200.
