Trac-lok questions

When I bought m 2000 TJ I ordered a Trac-lok rear LSD. I read somewhere online that he Trac-loc looses it's effectiveness around 70k miles. I have close to 80k miles on my wrangler. Questions:
1. Is there a way to test the effectiveness of the LSD that does not involve jackstands on the rear end?
2. About how much will the replacement LSD clutch pack cost (parts)?
3. Replacing the clutch pack goes way beyond my skills, which means going to the dealership or a local general auto repair shop I have used before. How long will this repair tack for a skilled mechanic who knows what they are doing?
4. Is there anything in this job that I would be better off going to the dealership for?
Thanks . . . jeff

For what it will cost to fix/replace trac-lok I would look into a true trac. much better unit.

Jack up your rear axle so both tires are off the ground. Shift the transfer case into neutral then spin one of the rear tires. If the other tire spins in the same direction, the Tracloc is working, at least somewheat. If the other tire spins in the opposite direction, the Tracloc's clutch is worn out.

For the cost of getting the Tracloc rebuilt with a new clutch pack, you'd be better off replacing it with a new Detroit Truetrac limited slip differential. The Truetrac is gear based, not clutch based, so it won't wear out or need a special additive like the Traclock.

I went to 4wd.com. Looks like the D35 truetrac runs about $400. I have a D35C rear. Will the truetrac for D35 work in D35C?

Question about the trac-lok. I have 3.73 gears in my TJ, in my parts bin I found a trac-lok carrier with 3.55 gears. If I put 3.73's on the carrier, would that fit into my D35 with the taller ring gear?

Should fit just fine. Caution that it's not all that easy to set up used gears since it's very difficult to shim them so the two gears mesh where they were previously work hardened.

I'm going to hijack my own thread. Now a Truetrac and axle question. I see Superior 35 alloy axle kits with 2 or 3 lockers (detroit autolocker, ARB, Ox). Is there a 30 spline Truetrac for Dana 35 alloy axle? Like others, I would consider Truetrac in front and rear. I'm ok with stock dana 30 axles (there should be a truetrac to fit d30 27 spline), but would be interested in beefing up the rear to handle 33" tires. Have not found any combination of Truetrac with D35 replacement axles. Also, if I go from 3.07 to 4.10 gearing, will these gears fit in the original d30 and d35 differential housings?

I don't believe there is a 30 spline version of the D35c Truetrac. However, Superior Axle makes a hardened alloy 27 spline c-clip eliminator kit for the Dana 35c where its axle shaft has the strength of the Dana 44's OE 30 spline non-hardened carbon steel axle shaft. I'd go that way rather than trying to get a 30 spline version of the Truetrac.
