there are 3 places to check for a wobble, 1 if you take the inspection cover out you can see the shaft and coupler, have someone steer back and forth and check for slop there, 2 in that hole there is set screw straigh up, adjust that do a little at a time because it will get tight when you turn left or right(make sure to turn all the way when adjusting) the teeth maybe too worn and you can only get a little bit out of it and no one makes the teeth yet 3 the shims are on the left side, you need to take the radiator out to get to it, there is a cover with 4 bolts the shims are behind that don't take out too many and crack the cover because that really sucks. ours needed all three. we needed a new coupler and teeth. good luck. if you need any help let me know
