Spent some time looking at archived posts but did not come up with a satisfactory answer to my question. Is my diff. a limited slip? I read that in a ea82 1988 loyal that the diffs were 3.7 but I also read some info to the contrary. My diff is a 3.9 and the p/n is 622006022.

 

Thanks

Clutch-Pack LSD:

NON-LSD

Most R-160s you see under Subarus will NOT be an LSD. There were no LSDs of any kind in 1995-1999 Subarus.

Look for the following Subaru part numbers (look at the foil sticker for part number and ratio):

7220 11010: 3.70 ratio

7220 11011: 3.70 ratio

7220 11012: 3.70 ratio

6220 06020: 3.90 ratio

6220 06021: 3.90 ratio

6220 06022: 3.90 ratio

27011 AA151: 3.90 ratio

27011 AA040: 4.11 ratio

27011 AA110: 4.11 ratio

27011 AA111: 4.11 ratio

The sticker would say LSD on it if it was, and they didn't make a 3.9 LSD, except as a rare option on the XT6, and I think that may have been the VLSD. At any rate, only turbo, full-time-4WD (AWD) 5 speed's for 88, and 89 got the 3.7 LSD (And some older RX's I do believe).

 

To verify - jack up the back, put the transmission in 4WD - turn the wheel - if the opposite wheel turns the same direction it's an LSD. If it turns the opposite direction it's a regular open diff.

 

GD

it is not a lsd. Thank you

also just for referance the sticker on the back of the diff also says lsd on it in large letters

I have yet to find one at PAP. Only seen the LSD sticker in a pix from this site. I always scrape the grease off the diffs to check, but I've noticed others do the same. Competition anyone?

I seem to recall that the Datsun 510 can use a Subaru LSD in place of its own rear diff, and that Datsun owners will even compete with us for those few rare ones.

 

All is fair, I guess, since Soob owners compete with Peugeot owners for their wheels.

exactly,

i know here in denver i have been beaten to two by kingbobdole and jerrydemoss found the one i pulled 20 min after me while i was running home for tools
