88 blazer 4x

i have another prob, i got my front axle to engage, but it wouln't disengage. Then i heard a hellatious gringing noise in 4 wheel drive on snowy roads and my right tire locked up... i checked my cv and the boots were cracked so i rebuilt it but it looked just fine.. could this be my front differental?? and if so has anybody ever bought one and changed it??

<font face="Comic Sans MS">That's not a good sign.... Does the front differential disengage when you pull the vacuum line from the actuator? Might try that. If it disengages that way, then the problem is likely that switch on the t-case. Mine is a little slow at disengaging the front.

If I had to take a guess I'd guess right hub bearing, or the front differential. I would check the hub bearing first, because it's easiest to check. [img]/wwwthreads_images/icons/crazy.gif[/img]

Never had to change my front, but it looks like quite a large project, even more so than changing out a rear.

You could also get a suction gun and suck some of the 90W out of the diff. and see if theres any metal shavings in it(i.e. whats left of the bearings). Find out what gears you have and I'll see what I can find as far as an IFS center section. Ouch! Sounds expensive! The front diff. is a pain in the ASS to remove-even after I pulled the drivetrain I had fun! Good time to add a Posi-Lock after you get the IFS replaced!
