I've gone through two DTT's in my Liberty with a 242.... shredded both of them, now moving on to a Eaton E-Locker. Both DTT's were under warranty and where installed by two different shops since I thought they were the problem. I'm getting pretty good at pulling my front Dana 30a out and back in.....
From day one on the first DTT, the steering was very heavy, then it started to slightly engage when going around corners, then finally clunking noises coming from inside the Diff over every bump in the road. For the longest time I couldn't figure out what the heck was going on. Once I pulled the front drive shaft, everything stopped and drove normal. Second shop said there were some old DTT part numbers that were of a lesser quality.... so i said sure, that must have been the problem. Second DTT did the same thing but this time I pulled the drive shaft immediately until I had time to pull the axle out again.
I never drove it in Part-time or Full-Time on the street, just in the dirt, gravel, Oregon mud and some snow. I figured that the DTT would outlive the Dana 30a.
That's just been my experience. All I can think of is that my 242 is having issues and maybe applying some front drive line pressure to make the DTT start to engage or something.
There are,well were,2 different DTT's that would fit the KJ's D30A,old style being 2 worm geared and the new style being 3 worm geared.One old style and one new style and both needed ring gear bolt spacers since both DTT's are drilled for 7/16" ring gear bolts and the KJ's D30A uses 3/8" ring gear bolts.Installer error is most likely the cause for your issues with the DTT's.I ran a front DTT for 3 years with zero issues and pushed my KJ hard offroad but made ring gear bolt spacers when I installed the DTT.My old D30A with the DTT is still alive today in a CRD.Had a slight increase in steering effort but nothing drastic and I rather liked it returned to center much more quickly then when it was open.
