Hey, I have a 96 XJ with the veritable D30 and D35 combo. The rear has a rebuilt Trac-Loc, but it just isn't giving enough grip. I was checking into the Lockrite for the rear and the Powertrax for the front. The guys at Modern Motors won't sell them because of problems and breakage. I just want some other feed back before I spend twice the money on a Truetrac. I have brand new 31-9.50-15 TSL Super Swampers on it, so won't be going to anything larger for a long time. Any feedback would be great.
