???I need advice...Recently we swapped out the front differential from a 79' into our 75' FJ40. This was to gain disk brakes. While we were at it, we added a lock rite solid locker. Now, on the trail, under acceleration the rig wants to turn one way, and under deceleration, it wants to turn the other. Trying to physically turn it against what it wants is very difficult. I know power steering would help, but it acts like something else is amiss. The 79' diff. appears to be about 2 - 3" wider than the 75' was. Could we have messed up the steering geometry? Any thoughts that could help resolve this are appreciated. We are taking the rig on the Memorial Day run at Clayton, OK and need to get this straightened out. Thanks. Chuck
