pinion angle setting will be greatly effected by when brushing you have in the arms or rear ears.. ......if rubber the they will flex more than poly, if heim joint they won't flex at all. the pinion will rotate upwards when power is applied this is because the pinion gear is trying to walk up the ring gear. the idea is to get the total angle both driveshaft and pinion to be as close to 0 as possible when running. pinion angle and drive shaft ujoint angle work together put at not exactly the same http://www.wolferacecraft.com/pinionangle.aspx downward pinion angle will increase initial bite. there is a problem with having too much traction too soon
Not enough water down on your burnout. As soon as it dried out the water where you started and it rolled into the dry area that's when your vibration started. I wouldn't worry, all the Buick geniuses will be in BG and i'm sure your car will return home in better shape than when it left. See you there ! ! !
Good input Ben, thanks. I was kinda thinking that to Moon!! Probably be tweaked while there under the supervision of those in the know. Looking forward to hanging with ya while you drink all my beer (as usual!!). Haha.
All you need is an angle finder. https://www.homedepot.com/p/Johnson...97&gclid=CJCNiv3Xn94CFRWxswodGT4Jdw&gclsrc=ds Just measure the drive train angle at the rear of the transmission. You want 0 angle under power, and the pinion moves up about 2*. So for example, if your drive train angle is -4* (pointing down), you set your pinion at +2* (pointing up). Under power, it comes up another 2*. Under power, the drive train points down 4*, and the pinion points up 4* for 0 angle. http://www.buickperformanceclub.com/Pinion.htm
I'll see if I have time to check/adjust pinion angle before loading it onto the trailer and leaving for BG. May just have to do it there.
Unfortunately just the old man's truck, clutch nor carb made it back in time, we'll be in the vendor area tomorrow. Several the GSR guys will be near the entrance to circle track
Your iPhone has a really handy and accurate angle finder built right in. Seems there is a way to access it now in IOS12 if not just download an app to access it. If you have adjustable upper trailing arms they can be a bit of a chore to adjust if you are trying to adjust them while the suspension is loaded unless you brought some stubby 1in (ish) wrenches.
