Cruise control cutoff and Crabbing (Axle adjustment procedure)

[Zimm]

My crabbing issue has been solved. it turns out I had a positive thrust angle. Interestingly enough though, they utilized an axle adjustment procedure for the cruise control to fix it. If youre having cruise cutout issues (I did) maybe your alignment is out also. It could be something to look at.

At any rate, heres the Cruise "fix it" procedure. Mine did not cut out on a 5 hr drive, which it always did a couple times, so maybe it works. It did fix the crabbing issue.

I'm still clunking like a junker. they did the auto trans reset again, and it still has the 3-2 shift delay issue, and still only clunks during 3-2. when i left the house this morning, with a cold transmission, it shifted fine for 5 stop signs. on the way back with the the trans at temp, it clunked on every 3-2 thru the same signs.

What is “crabbing” ?

IMO crabbing is when the vehicle is out of line and the front and rear wheels are not tracking the same line. From a visual point of view, it will appear to be slightly side on, going forward...if you can get any sense out of that, that's my take on it

its caused when the rear axle is out of alignemnt..

say you take your rear axle and extend the passenger side control arms 1". the truck will now turn to the drivers side. to counter act this, you will need to point the front tires to the passenger side. so, to drive straight, the truck will look like its body is crooked, much like how a crab shimmies sideways, or if you watched a dachshund run down the road with it bum off center to one side. If your front end checks out as perfectly aligned, but you still need to to turn to one side to go straight, theres a good chance this is your issue. An easy check is physically measure your wheel base, if one side is longer, and you need to point the wheels to the longer side to go straight, have it looked at.
