Outsource Posted January 14, 2007 Report Share Posted January 14, 2007 I just boat this at Sears in the hopes that it will help me figure out my pinioin angle problem. Will this work? After installing the spindles and shackles I have the pinion angle vibration in the rear. I installed 2 degree shims and still had the vibration. I added another 2 degrees to make it 4, and still have the vibration.....in addition, now I have a vibration upon braking when I come to almost a complete stop. The vibration happens at about the same speed on acceleration and braking.....around 15mph. Belltech said the 2 degree should have been enough. They want me to try 3 degrees. If that doesn't work I'll try 1 degree. If that doesn't work, I returning the truck to stock height and giving up. Any suggestions other than what I'm gonna try?

pimp ss Posted January 14, 2007 Report Share Posted January 14, 2007 I noticed a vibration in mine after i lowered it 2/3.5 i checked the pinion angle on mine and on my buddies stock sss they were exactly the same so i think i need to have my tires balanced they have not been balanced since i got my new tires 10000 miles ago.

kckid Posted January 14, 2007 Report Share Posted January 14, 2007 Yes that will help you find your pionion angle, that is what I use. What is it at now? Mine is lowered with hangers and shackels and I had to use 6 deg shims to get it into spec. Quote Link to comment Share on other sites More sharing options...

Bad Bowtie Posted January 14, 2007 Report Share Posted January 14, 2007 What about NEW "lowered shocks"? This might also help to remove the vibration ur describing. Quote Link to comment Share on other sites More sharing options...

Outsource Posted January 14, 2007 Author Report Share Posted January 14, 2007 How about if I remove the shackles and install the 3" leaf packs? This will retain the stock pinion angle, right? Quote Link to comment Share on other sites More sharing options...
pimp ss Posted January 14, 2007 Report Share Posted January 14, 2007 i did the shackles and hangers in the back my pinion angle is the same as my buddies stock truck. Quote Link to comment Share on other sites More sharing options...
04CHASE Posted January 14, 2007 Report Share Posted January 14, 2007 when doing hangers and shackels the pinion angle will change no matter what. the beltech leafs have a shim so they will retain the stock pinion angle( ask kaotik1) Quote Link to comment Share on other sites More sharing options...

When I bought it it was dropped 2'/2" with shackles and spindles. It does it with winter and summer wheels, so I'm confident it's in the pinion angle. I've heard alot of people of this problem. I've added a 2 degree shim in the spring but the vibration still exists while accelerating quickly. I'd love to get rid of this issue, so any advice you can give me would be greatly appreciated. It appears several people have had this issue, so I'm sure somebody has corrected the problem. Any advice is greatly appreciated. Thanks, Bill Edited December 14, 2008 by bad88t-top (see edit history) Quote Link to comment Share on other sites More sharing options...
