Front TruTrac not right?

So I just got my truck back fron the getting a trutrac installed in the front diff (I trust the mechanic) but it now pulls to the left under acceleration only. When I let off the gas or engege the clutch no more pulling sensation. I have had a Detroit Locker in the rear for awhile and it was almost unnoticeable. There is some play/slop in my steering but not bad. It just seems weird. Any thoughts? Heading up to Wintergreen this weekend should I be worried?

I found it! Torque steer is what I have. I guess it gets better when broken in.

How'd you figure that out? Locking the center diff and seeing if it continued?

I have a trutrac front and rear... When I drive it always wants to self center. Should not be torquing to the side... All the literature I've read on them is that it centres your wheel which makes sense as it transfers torque to the tire that isn't moving as fast ( inside turn tire) which speeds that one up...

Yep got torque steer for awhile with the TT and it went away after it broke in so for me I experience exactly what you did. I may be off base but I thought it may have something to do with unequal length half shafts

My Detroit rear was really tight at first. After a few thou miles it "softened" becoming barely noticeable as it unlocked and relived.

I have 90k + miles on my TT/Detroit set up. I'm also running 4:11's which tend to magnify everything a bit. My TT has been a trooper. About 6-7 years ago I was spinning at high speeds trying to exit a thick heavy sandy mud pit at MAR when my front DS twisted like taffy in two. TT never faltered.

Check tire pressures and wheel bearings. Any drag on one side or the other causes the TT to do that IME.

One tire is newer or different pressure giving a different overall diameter and when both turn the same speed, one travels slightly farther causing it to pull to one side.

Sounds like it did not take to long to break in. You had me a touch worried as this is the route I am going.
