Car Forum / Chevrolet / Chevrolet Trucks / June 200894 K1500 no low range
94 K1500 Silverado. Put it in low range yesterday to pull a tree. First time in low in years. It goes into low, the 4x4 indicator lights come on, but the front axle isn't getting any power. Works fine in 4 high. 4 low worked fine the last time I used it. Suggestions?? Bill Check the vacuum hose to the ft axle actuator. > 94 K1500 Silverado. Put it in low range yesterday to pull a tree.

Hmmm--OK, but it engages fine in 4 high. Isn't the front axle actuator on a 94 electric? Bill >> Check the vacuum hose to the ft axle actuator. > > Hmmm--OK, but it engages fine in 4 high.

Correct, it is solenoid operated and if you have 4 hi the axles engagement is ok, sounds like a transfer case actuator or internal. >>> Check the vacuum hose to the ft axle actuator. >> [quoted text clipped - 3 lines] > > Yes...the other poster is thinking of an S-10 type rig.. ----== Posted via Pronews.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.pronews.com The #1 Newsgroup Service in the World! >100,000 Newsgroups ---= - Total Privacy via Encryption =--- >> 94 K1500 Silverado.

If it's electronic the transfer case actuator may be binding. If it hasn't been used in a while try shifting it a few times and see if it clears up, could just be some crud on the switch on the encoder not telling the front axle to engage. You are shifting it into low with the transmission in neutral?  SignatureSteve W. > Electronic shift transfer case or manual > shift?

The indicator light for the front axle engage comes on, and I thought that worked off of a switch on the actual engage fork. Starting to think it's internal, but I've never seen one before that would drive the front in 4H but not in 4L. Nothing crunching/growling/knocking at all---just no power going to the front in 4L. Bill | > Electronic shift transfer case or manual | > shift? [quoted text clipped - 20 lines] | | Bill Sounds like a broken shift fork. There are 2 in there. Cheers that year used a coil heated oil to move the axels together. often faile and should be replaced with 1999 ?? or?? which uses a coil driven plunger to lick the axels. it was 110 dollars including cable, and took about 1/2 hor to install. easy fix and it always engaged. old oil type would fail to heat and expand oil when cold old john Hello, BillM!
