4x4 problems

[98torch]

i have a 98 silverado z-71 that will not go into 4x4. when yo put it in 4 low the tranfer will shift it in but i have no pull in the front tires. i cant seem to figure out the problem

4 HI works?

[98torch]

negative no 4 hi. it wont even spin the front shaft with the tuck off the ground

What transfer case? Automatic or manual t-case? How do you know the t-case itself goes into 4 low?

[98torch]

it is push button 4x4 but does not have tthe auto button. i know it goes into low because you can hear the change and you notice a difference in torque to the rear wheels

[GM-Tech]

Well, it gets a little more complicated. Lots of things in the electronics could cause this. Need a code, which I'm sure is probably stored.

someimes while driving, i will try to lock it in and the front end sometimes wants to grab but the sometimes not. it is likee sometimes it wants work and sometimes not. i think part of the problem could be the 163,000 miles on it and also the 35 inch mtrs

i ahve been thinking about a solid axle conversion on the truck and have been thinking about maybe putting in a np205 tranfer with i a manual shift lever. do yuo tink that this would be a possible configuration

I don't get into modifications. Sorry, can't help ya there.

[98torch]

i think i fuigured out what the problem may be... i drained the transfer case and found out that there was a snap ring come loose inside the case. tomorroww i will be taking the case out of the truck and rebuilding it. do you have any methods for doing this that will maake it easier or faster?

Nope. Never rebuilt one myself.

do you know where i can get a diagram of the internals so that i put them back the way they are supposed to go

Buy yourself a service manual. It'll have full instructions on disassembly and reassembly. Dunno if you can find something like this on the web, but I doubt it.

do you think the port and polish job and the full exhaust and intake and the high flow fuel system and the 35 mt/r's and the lockers has anything to do with the t-case taking a s**t
