Chevy Silverado and GMC Sierra 4x4 Questions
My 2000 G M C 1500 electric shift to 4wheel drive works just part of the time. probably trouble with the shift motor at transfer case ? also the right running light burns out every few weeks and the socket is badly burnt.
I would not recommend another Chevrolet to anybody. I am almost ready to trade off for a Toyota or Ford. This is the worst vehicle I hae ever owned.
Would like to know if anyone has done a 2/4 lowering job
on a similar truck, who could give me some info on a kit, etc.
Up to what speed can I switch between 2wd and 4wd high?
The steering is a little loose on center... I can waggle the steering wheel a few inches either way on center without the vehicle veering left or right, is this "loose" steering normal with these trucks? I used to own a 99 Ford Ranger and the steering was alot tighter...
Finally, there's a little shimying in the steering wheel at cruising speeds... the truck was aligned a few months back, so I guess that could be unbalanced tires, bad tire pressure, or that it needs re-alignment right?
Parts Repaced: Dash Switch and 4WD Frt Axle Actuator
1. Defaults to 4HI after I switch the ignition on 5 sec off 5 sec then on 10 sec.,will also switch to Auto 4WD.
2. Depressing dash buttons runs 4WD Frt Axle Actuator with whining then vibrating grinding noise at end of cycle. Acts like the actuator is trying to shift gears but overloads, then shuts down when trying to switch to 2Hi or 4Low.
I Checked fuses, left side drivers door and ATV under hood, OK.
Low Fluid level possible ?

Well i hit the whole and bounce twice and everything just goes out lights radio every thing i was wondering if anyone new what this was, about 1 min later it turned right back on and cranked like a chevy does quick and easy and drives fine. I would appriciate some feed back, thanks.
this is the best place i have found for parts price: autopartsdirecttoyou.com
good luck !
I was like you and I changed the front and rear differential fluids along with the xfer case. I believe that the manual says something possibly with the xfer case and that my have to do with the fact that the Z71s have the automatic xfer case or the auto 4wd button. The last time it came on I changed the front differential fluid and hasn't come on since.
That is interesting. :surprise:
on the way to work a couple days ago at 75 mph the 4wd just kicked in by itself..couple loud bangs seconds later came from the front wheel area.
anyone ever have this happen?
was stuck in 4wd for 10 minutes or so till i finally got it out into 2wd then pulled the fuse for the tranfer case so i could make it to work.
just had 2 front tires put on..slightly different from the rear..heard this could be the problem as you need to match them perfectly.
asked 5 diff friends and got 5 diff answers.
also isnt there some kind of failsafe so this wont happen if it happens to be a short in the switch?
drove it home with the fuse pulled (about 50 miles) with no noises..seems to be ok but im afraid to put the fuse back in till i find the exact problem.
has an automatic tranny.
Did it shift into 4Hi or 4Lo? If it was 4Lo, then the problem is not in the front diff. - the diff. doesn't have two speeds.
Once you figure it out and do the repair, make sure you take it offroad and put it through the paces to make sure there was no damage. You don't want to find out when you really need 4x4 and it's not available.
thanks for your help!
I have the AutoTrac system and when I go to turn the truck on, sometimes it says it is in 4wd, auto or neutral. It then tells me to service 4wd, no other lights are on and I'm not turning on anything...
Most the time it is normal and in 2wd when I turn it on.
Mechanically the sytem works like normal when I want to go 4wd I just push the button as normal and it works...
You've probably got a bad bearing somewhere but without more info. it is impossible to diagnose. Could be wheel bearing, transmission, transfer case, rear diff. Does it vary with vehicle speed or engine speed? Example: If it's a power steering pump it will make the noise under the hood even though the vehicle isn't moving. Rev the engine with the hood up and listen. If there is no noise it is somewhere in the drive train. You could put all 4 corners up on jack stands, have someone put the truck in Drive, and listen to each wheel bearing as the wheels turn, and crawl around underneath and see where the noise is coming from - transmission, transfer case, etc. Be careful with that, make sure the truck is secure before doing anything like that, and don't get any loose clothing near any spinning items in the drive train. Even if you find the location of the noise it might not be something you can repair yourself unless you are very sophisticated, in which case you probably already know what I've just told you. Good luck.
I have been told,and the manual says that i can "shift on the fly" from 2 wd to 4wheel high at any speed below something like 45 miles per hour,and back. When i try to shift from 2 wheel to 4 wheel at say 25 mph ,its like shifting a standard tranny without the clutch.
I guess i'm expecting that the S.O.F. to be smooth. Truck has done this since new, especially when cold. Manual says you can shift while truck is in motion.
Thoughts from 4x4'rs appreciated.
Also sector shaft bearing in the transfer case replaced again by dealer $ 610. The sector shaft connects the transfer case motor.
Personally my opinion, with the thousands of dollars I've spent on 4wd repair and the additional cost to the truck purchase for auto 4wd.
GM should go back to manual shift, they cannot seem to get it right.
it could be the actuator motor on the transfer case that is your problem or it could be my most recent problem the sector shaft bearing in the transfer case.
I am new to the board, and have looked for a similar problem as mine, but can not find one.
I have a 2005 Z 71, with push button, 4WD, and the "auto" mode. I drive in 2wd, 30 minutes, 75mph, each way to work. Tranny works fine (with chevy's normal rough shifting) The other day I noticed the red light next to "neutral" was on instead of the amber light next to 2 Hi. The truck was running fine, and when I pushed the 2wd button, amber flashed for a few seconds, and went off. I pulled over, shut off the motor, restarted, and it apperantly reset. I thought life was good. Now I have noticed the red light on three more times, and it doesn't reset by simply restarting. It is very random when it is on, or off.
Any simmilar stories or advice?
