4 low

[Riche]

Hey guys,
A newbie to the forum here. I just bought a 1997 Z71 ext. cab. I need some transfer case advice. My 4 low is not engaging. The light just blinks. I think the front axle is engaging b/c you can feel the difference the steering in 4 hi. (i.e. the tight steering effect of the 4 wheel drive). 4 low feels the same I don’t think the trans case is changing ratios.
Any advice?

And when I start it up in the morning the first 25 feet the truck rolls I feel some kind of metal grinding noise from the front of the truck(it will only do it if it is rolling). Kind of like bad breaks(metal on metal) it only last a second. And the lights (dash & headlight) usually dim(weird???). It will not do it again until I let the truck sit for probably 4 hours.

Anyway you may think that I bought a pile but the truck is in relatively good shape the engine/trans are strong. And the exterior/interior is clean. I plan on rebuilding the front end and I fell it will be a really good truck. I would appreciate any advice with my dilemmas.

Thanks in advance!!!
Richard
