Not that hard as long as you can get the trailblazer high enough to drop the front differential axle and pumpkin. You have to unbolt the two CV Joint on the inner side and then disconnect the front prop shaft (Drive shaft), the hub locking assembly. Then it's just unbolting the pumpkin and axle shaft from the front frame mounts and dropping it one side first. If you can get under the trailblazer you can see what i am taking about. Good luck and hope this helps. Takes about 45 min to drop the old one from a lift and the right tools.

Front and rear diff on olds bravada I was wondering if I should drain and add gm fluid with gm additive


if the diff oils is in need of a change then it would be wise to change the oils
if the additive is an approved GM additive then it will not hurt to add it
just make sure that the diff's are not limited slip diffs as they require a special oil and then the additive may not be suitable for the oils

I have a 1994 Chevy 1500 z71 I have replaced the front diff with the same gear ratio and know my four wheel drive is binding up and idk what is causing it to do that I need help


4wd vehicles in the main do not have 3rd diff in the transfer case (unlike all wheel drive vehicles) to allow uneven torque between front and read diffs to dissipate
that means that if you are driving on hard surface ( sealed roads ) there becomes what is referred to as a torque wind up in the drive train .This places all gears ,chains under extreme pressure and prevents gear changing ( shifting out of gear)
To overcome this problem, only select 4wd when driving in snow ,rain, mud, gravel or any surface that allows the wheels to slip and so even out the torque wind up.
If you had to replace the front diff that may have been the reason as front diffs are predominently weaker than rear diffs because of the way the teeth act on each other and the torque wind up will break the weakest part

2005 Yukon Front Diff Axle seals


You don't have to remove the whole diff to change the seals, but you will have to seperate it where the shaft meets the carrier housing. There is a clip holding the passenger axle shaft in place that you have to remove to change the seal. The drivers side axle stub can be removed with a little force as there is a spring clip holding that side in.
