Re: Pitman Arm bolt size
The nut is torqued to 100-150 foot lbs. per the service manual, and 175 foot lbs per Moog. 135-140 with oil should be about right, but use search to verify.

Re: Pitman Arm bolt size

Re: Pitman Arm bolt size
Interesting. I thought I read 100-150 ft. pounds someplace, and your chart made me question that. The assembly manual reads 100-150 ft. lbs., MOOG more than that. In hindsight, I think I'd have torqued it 135ish with oil, not 150.
