2001 Suburban 4x4 will not connect

I use to owen fords three things common the control board BRAIN for the 4x4 ,fuses, or last the cilinoind on the transfer case

One thing I can think of is that the steering gearbox adjustment is too far from the pinion and needs to be tighter. But then your mechanic would have known this and reset it. Only other thing could be that you have the incorrect backset in your front wheels and that would make the vehicle squirly at speed. That happened to me when the wheels I stuck on my vehicle were outset too much. Other than that, only other thing is there is no toe in on the front end. Without a certain degree of toe-in, there's no drag at all and the tires will flop from left to right at will.

Hi,
If you have a Four-Wheel Drive Suburban, it sounds like it's in 4WD HIGH. Check the switch on the dash and change to AWD or 2WD....do not use the 4WD Low (unless you're stuck in mud).
Td

2 unless you have a 4x4 or a two piece axle. Get under and look, if your axle is one long ppiece 2, it it's a two piece axle, 3

Yes, it going to be your water pump....if you buy one, make sure it is the right rotation....They make a left and a right.....

have a look at your bearing on that side

does the shake come and go at different speeds? check your tie rod ends by lifting the front wheels off the ground and grab the tire and shake from left to right. if they are tight you probbably need to replace the rotors

buy manual

your 4x4 electronic control switch may have gone out and that is why it is stuck in that gear it is located on the transfer case i beleave its on the right side its black with a couple screws holding it and wire coming from it but i may be wronge and it could be on the left been a while since i had to change one

odometer cluster in my 2001 model suburban 1500/ goes on and off when i hit bumps or when i turn car off can you tell me whats wrong with it or do i just need another one.
