Hello to all the fellow GMT users on here. I am new to forums but think I have the gist of it. I have recently been having trouble with my 4x4 not engaging in my 2004 trailblazer. Switch it over to 4hi and the actuator and transfer case whirring sounds are present and the indicator light switches to 4hi and stays lit up solid. Jacked up all 4 wheels and switched to 4hi and had someone let met get a look at the front drive shaft and it is turning so I figure it is not the transfer case. I also noticed a while back that the differential has a leak somewhere and have added fluid a few times. Since I have owned the vehicle I have driven it around 85k and the odometer now reads 183k. I have not had 4x4 for around 20k now. Now that I want it fixed, I check the front differential and it seems to be pretty dry (could barely find fluid in the bottom). Before the 4x4 problem happened I would switch over to 4x4 stuck in sand and accelerate but the back wheels would continue to dig for a few seconds, then the front wheels would kick in after a big noise (grind or thud) in the front end and run smoothly after that. I also checked the sides of the differential casing for metallic material and found that my finger was sort of glittery.
Since then, I have been looking for a used front differential and have found one for a 2002 trailblazer. I was wondering if it would fit my 2004 or if I'm even heading the right direction? Thanx for all the useful info.
