Wj Standard or Vari-lok differential?

I have a 2000 Grand Cherokee with 4.0L engine (4x4). I'm going to change the gear oil in the rear axle (and in the near future, front axle). I have Select-Trac (not Quadra Drive).

Do I have a starndard differential? If so, I don't need to add friction modifier, right?

thanks

Correct. You have a regular diff, so 80w-90 will work. No FM needed.

Typing on phones sucks.

Do you have a D35 or a D44a? If its a 35, its definitely not a vari-lock. If its a 44a, it could be. The rear was an option from the factory with your setup. There should be a tag between the bolts on the diff that will say "lsd" if it has vari-locks. Chances are though, its just an open diff.

I'll use 75w-140 full-synthetic gear oil. I don't think 80w-90 will work for me.

thanks

From wjeeps.com:

The Rear Beam Iron axle has a cast iron differential housing with axle shaft tubes extending from either side. The tubes are pressed into differential housing and welded. The axles are semi-floating supported by the axle shaft and bearings. The axle shafts are retained by bearing retainer plates on the axles which are bolted to flanges at the outboard end of the axle tubes.

3.75 pts. (60 +/-1 oz)
Bolt torque:
Fill Plug: 25 Ft. Lbs.
Cover Bolts: 30 Ft. Lbs.

Axle Ratio:
3.55, 3.73

Axle shaft:
27-spline, 1.16-inch thick

Thermally stable SAE 80W-90 gear lube

For heavy-duty or trailer tow use:
SAE 75W-140 synthetic
MoparŪ P/N 04874469

NOTE: Trac-lok and Vari-lok equipped axles require 4 ounces of Limited Slip Additive be added to the lubricant.

FYI - I changed the gear oil in the rear differenetial this morning. There is a tag clearly marked "75w-140 SYN" on the diff. I'm glad I bought the right type, Valvoline 75w-140 Synthenic. $12.99 each bottle (two bottles are enough for the rear axle) from Pep Boys.

I stand corrected, but got pics of the diff? Someone might have swapped a Vari-Lock in there.
