Changing C2 Trailing Arms

Re: Changing C2 Trailing Arms

Your right now that I think about it...The lack of a dial indicator was puzzling....IMO it's the most important part....It looked like he was just setting them by feel. Isn't correct preload on the bearing key?

NOT pre-load. That's what you don't want. There needs to be END PLAY in the 0.001-0.003" range. The only way to measure that is with a dial indicator.

My bad... I used the wrong term....End play...It's very clear in the shop manual procedure.

Joe,Just a note, Tom's sets his 31 spline axles to 10 in/lb preload and they work fine but I stay with 0015-002. I am building a set of 31's now and just set them up. Checking endplay is very subjective to loading, I was able to get 0015-002 but they also have a near preload condition as checked in normal state. They are smooth, no lateral play, and I expect them to last many thousands of miles of abusive racing. The 31's use the larger bearings on both inner & outer and a different inner cup. The way the video shows setting the play appears to be by feel and that is only one of several things I saw that was concerning. I think there is a wide range of tolerance they may run at, hence the 001-008 endplay but that is general setup. Holding tight tolerance work requires precise measurement and machine tools to achive, I didn't see anything remotely close there.

Matt, here's an old article by Gary. I guess you ignore the press as he just said he does'nt use it anymore. I've found his articles very helpful.
