Hi,
My 4 wheel drive will not work on my 1995 GMC jimmy. Mechanic said it was the cable. I have no idea, so I go on the intenet and buy a ACDELCO US 15721261 Trans Shift Cable
4wd ; 4-speed At (m30) ; Chevrolet (x88) ; Gmc (z88); Years:1995-1996; Per Car Qty:1; from Bestvalueautoparts. You quessed it WRONG cable.
 
My mechanic said the cable is about 18" to 24" long. Thats it no other info.
 
Does any one here have an idea what cable I need and where to get it?
 
Thnaks for any info
Frank

Also my 4 wheel drive is not the button style. Its the shifter type if that helps.
 
Thanks Again ,

I have a 2000 Jimmy which did the same thing, First thing is look under the hood, in the middle of the fire wall is a vacuum switch, check and see if all the rubber hoses are connected and you do not have a vacuum leak. then check your push button cluster o your dash, mine was bad and needed changed out. After I did all of that mine works great with no problems. Good Luck my friend

Thanks for the info. Funny thing is that I did that exact same thing two days before I received your comments. My acuator valve (switch) under the hood was gone. The way I tested it was I taped the two hoses (that go to the switch) together and went into the vehicle and tried the switch again. Worked like a charm. Then I went and bought a new valve/switch and it is still working. Thanks to everyone for their help. I just hope this info helps someone else. Best site every.

Front end noise in 2wd goes away in 4wd by jbagz

i have a 1999 GMC Jimmy 4wd 4 door, i was driving to work when i heard a noise that was getting louder that the stereo. I turned the radio off and listened, at low speed say 10mph it is a clicking/grinding noise, if i put the vehicle in 4wd the noise imediatly stops, when i switch back from 4wd to 2wd decel, then acelerate again the noise comes back, if i go 20mph or more the noise becomes a loud howling sound that gets very loud on decel, but once again if i click 4wd the noise imediatly stops. about 4 days prior to this happening i replaced the heater core, although i don't think there is anything i did to disrupt anything to cause this problem. I did notice that when taking sharp turns in 4wd i heard a clicking sound, so i jumped the gun and replaced the cv shaft on the passenger side cause that is where the noise was, i no longer have that clicking noise although the original problem sound is still there just as bad as it was in the first place. i hear wheel bearings are an issue although i would believe that when puting the truck in 4wd i should still hear the sound. any ideas would be helpful? thanks
Jon

You may as well take it to the shop. Sounds to me like the small gear in your front differential is burred and now wont work right. (hence the noise)
 
Only way to fix it is to replace the gear and also the nylon washer in your front differential.
 
This problem can be caused by poor vacuum not pulling the cable all the way to fully engage or disengage the gear. once its burred it must be repaired. Also check to see if you have a vacuum problem.
 
Just my 2 cents. I had the same symptoms as you and that was my fix.

thanks for the info, to replace this gear does the dif case have to come out of the truck, or is it on the black housing going into the case with the electrical conector?

The gears are in the case. I am pretty sure the repair was done without removing the differential from the truck.
 
The only thing inside the black housing is the connection for the cable. Parts cost was under $250.00 and labor was under $150.00
 
Unless you have a working knowledge of the differential and parts involved I wouldn't recommend doing it yourself.
