dmaxalliTech : Just checking to see if there is a typo on the front-upper shock torque being only 15ft lb whereas the front-lower is set at 110ft lb - seems like a great differential and sure want to do it right!

Really appreciate all the helpful items you put out here for us - all in such a cheerful mode!

Quite a difference between Erics specs and the last post regarding the "front lower" torque specs or am I reading it wrong:


is it 18ft lb or 110 ft lbs?


thanks

These are the front suspension specs for an 03 GMC Sierra. I think Eric might have mistyped the 110 lb ft spec.

Thanks, never would have guessed that high for lug nuts! I think my Jeep is 80 ft-lbs.

I'm going to be doing my first oil change in a couple of weeks, (boy, 500 miles goes quick when you're having fun!
).


I heard somewhere here that the oil filter has a torque spec.


Any advice here would be appreciated.


I will be putting Baldwin B1441's on. Running Delvac 1300 until 10,000 miles.


Well any torque on the oil filter?

Thanks Eric,


I remember where I saw it now. Mackin put a post about the correct oil viscosity (TSB section), and he must have pulled it from GM. He listed the torque as 18 ft-lbs.


That would be about 1 turn from contact.


You aggree?
