I recently bought a 2005 Subarau Outback Impreza Sport. The car runs great, I can almost say I'm in love with it. I do not however have a ton of familiarty with the rear differential in this vehicle. So when I turn sharp at lower speeds this car shudders. This seems to be coming from the back end, and generally eases when I turn at higher speeds. The person who sold it to me had his uncle rebuilt the diff which scares me because its a hard repair for seasoned mechanics. When I asked him about this one issue he respnded with this
I'm wondering should I be concerned or is this normal.
Well of course it's not normal I've driven ones that don't do that I would be very suspect of a guy who rebuilt one of those differentials I know machine shops that won't even touch those things
What do you recomend? Should it be rebuilt? or am I screwed?
I've never heard of that symptom being "normal" on any vehicle. Possibly the wrong lube was used? Might be worth draining and putting in the factory lube for limited-slip. Other than that if it's really bad, maybe install a low-mileage used replacement from a junkyard.
Differentials are really, really tough to get right and one "rebuilt" by some random person's uncle would be suspect unless said uncle is known to be a differential expert.
