I have no clue
Throw your thinkin caps on boys. 1999 EB Exped with AWD. While driving at speed and the trans downshifts out of OD (ie a climb), or accelerating hard from a stop, I get a clunk from the front end and then it feels as if the 4WD is trying to engage repeatedly.
Does not occure in OD
Only feel it after trans down shifts or on hard acceleration
Recently blew a tire and put down the original spare which is the exact tire as other three only no wear. Other tires are around half life or slightly more remaining. New tire on right front.
It's got 130k miles, mostly highway. This has been a great vehicle and I want to keep it so.

Ok, not good. I just took it for a spin and put it in 4WH. It engaged and was fine in a straight line. In a turn I got a horrible bind popping and grinding sound. The worst I've ever heard. I'm gonna jack up front end and check for bad CV joints and steering and suspension parts.
Help boys!!

There is almost exactly a half inch difference in hieght of the tires. There is no way to adjust that much with air pressure. Can i dissable the AWD via a fuse to get me through for a few days. I have to drive about 8 hours on freeways this weekend. I've put 2300 miles on this thing in this configuration, have I damaged my 4WD system?

you should be ok if it doesn't try to go into 4wd but I don't want to tell you it'll be ok then it break so my recomendation would be to get a new tire for the other side or see if you can find a used tire

Well that seems to be it. A tire with about 40k miles vs. one with 0 miles. I took out the fuse #104 and all seems to be fine. I'm pissed that I have to go spend another 500 bucks on three tires (to match my new spare), but I'm happy the system works. I just hope that when I put the fuse back in with the new tire I don't find that I've damaged the system in anyway.
Thanks guys

You can temporarily get away with buying only one tire instead of three. You would have to put it on the opposite axle from the other new one. Since the first new one is on the front, the second new one would go on the back. Having one old and one new tire on each axle will cause them to turn at the same number of revolutions per mile.

nice though but that won't work, the truck has two sensors on the front axle one at each wheel so you need the same size tires on the same axle and if you have different size tires in back with a limited slip it will be slipping the entire time the new wheel doesn't need to turn as much to go as far as the shorter wheel

I meant it just as I wrote it, "one old and one new tire on each axle". The two front wheel sensor have nothing to do with regulating the 4x4. That's all taken care of within the transfer case circuitry.

in normal driving with correct tires most power is going to the rear if it sees one tire going faster then another tire it takes power away from that axle and on the newer ones with traction control it will even use the abs to apply the brakes to the slipping tire so when it sees two tires on the same axle moving at different speeds it gets confused
