2005 Chassis Lube (U-Joints...)
Hi -
I've recently bought a 2005 Tahoe Z71. This is the first vehicle that I've owned that requires a chassis lube. I picked up the appropriate grease and a gun, and went to it while changing the oil tonight.
I found 4 zerks on each front wheel assembly: upper and lower ball joints, and inner and outer tierod. Are there any other up front?
The rear drive shaft had one on each U-Joint, but I couldn't access them with my gun. Do I need a special attachment to get to these? A flex hose attachment? What is the proper way to rotate the driveshaft to access these ports? Jack up the rear and and put the tranny in netural? Do the factory u-joints require lube, or are these aftermarket?
Should the front drive shaft u-joints require lube? I couldn't find any zerks.
Thanks!

Welcome to the forum. You will probably need a needle fitting for your grease gun to do the U-joints. I suspect that they are aftermarket cuz I can't remember the last GM car or truck that had zerks.

What is the proper way to rotate the driveshaft when the car is being worked on? Assuming all 4 wheels off the ground...
Thanks!

So I found the Idler Arm ones. I have no idea where the Pitman arm zerk is, or what/where the Pitman Arm is for that matter. Any pictures, description, etc. you could give me to point me in the right direction?
I also tried the u-joints on the rear drive shaft again with flex hose on my grease gun, and I still couldn't get the fitting over the zerk. Any one have any other ideas?
