I just bough a 2001 Subaru impreza outback. I am not familiar with the the limited slip details for this differential. I noticed that the rear wheel has a hop at low speeds and tight turns. I was looking for a course of action appropriate for repair. Does this rear require a modified friction lubricant? any particulars I should look for or has any one else experienced this issue?

You may want to look at your hub assembly bearings. Subaru has a problem with the wheel bearings going bad but not much trouble from the differentials. Search the forum for your symptoms and you may find an answer or at least something to point you in the right direction.
If I remember correctly, the differential does not require the limited slip additive.

do a search about 'torque bind'

all 4 tires need to be identical and near each other in wear-level

if you have an automatic trans, try the FWD fuse, if no help with that, could be a Duty C solenoid issue, or you need a replacement trans from a wreck.

if you have a 5spd - notice if the symptom is better when stone cold - then comes on strong after 10-20 minutes of driving. If so, center diff viscous unit is bad, best bet is a lower miles used trans from a wreck.


used units - check car-part.com or LKQ

Cheapest trick to give you a sense of hope.
I can hear the experience this statement... almost makes me sad.. lol

But the LSD in these cars are a sealed "viscous coupling" unit and do not require a special additive.

As others have said, this sounds like the infamous "torque bind": shuddering under tight turns, a "holding back" sensation, or growling/groaning while parking in reverse.

There are several threads and a nice FAQ/sticky up top about the issue.
