Hello,
I am just finished up replacing all of my front end outer bushings and seals. As well as the front axle u joints. The wheel bearing preload is set by 6 bolts. The OE service manual has the torque spec for these bolts listed as 162 foot pounds. The bolts are a grade 12.9 with an M10 x 1.5 pitch thread with a . I felt like this was way too much and I hesitantly began, I got to 80 foot pounds and then set the wrench for 120 and just felt like I was going to break something. I don't think the torque spec can be right. Any thoughts? I don't want to break anything. Any help is appreciated. Thank you.
