After lowering my 64 suburban, 3" in front and 4" in the back, how do I get the correct (the same # of degree's) drive shaft angle on the front and rear U-joints? I can shim the tranny mount but what about the rear end? Thanks From a new member.
hey new member. through my experience with these differentials you can either move bracket angles and there are some aftermarket people who make differential mounts or what idid one my 64 for performance was had a fabrication buddy do was build brackets that bolt on to the two trailing arms up front with an extra hole on top and bottom and it makes a big difference on traction. theokie64
[updated:LAST EDITED ON Dec-30-02 AT 04:28 PM (CST)]Burb ! I have a 64 panel. Front dropped 3 1/2 with spindle,springs and shocks, rear dropped 4" with springs and shocks. I'm not having a driveline angle problem. (?) I'm not positive if you really "need" to get it back to the same degree that it was at stock ride height. Just don't exceed the recommended angle. ( does 15 degrees sound right? I forget) At any rate, I've had no evidence in two years of excessive U joint wear or anything else that would indicate a problem as a result of pinion angle. Oops, forgot. I also have a one piece drive shaft too. DValentine
Funny driveline story I seen some pretty wild driveline angles on the lifted 4x4s at my high school, but then again, none of those guys know what they're doing. A few months ago, I went out to my truck to leave school. I was a little later getting out to the parking lot because I wanted it to clear out before I left. There was a group of students hanging around their imp*rts and messing around and one guy did a decent burnout. I guess that some others wanted to join in. Somebody in a lifted toyota pickup drove over and got ready to do one. He gave his truck a nice high rev in nuetral(!)and dropped it into gear. Instead of spinning the tires, or moving the truck at all, the drivshaft broke the U-joints and fell to the pavement. I never though I'd stop laughing! I guess the moral is to play nice with your truck. . . --TrustyRusty
