Re: Another Pinion Angle Question

Thing is with any measurement like the 3 degrees or your 5.5 is what it is measured against. Is your measurement with a level frame? Also the angle of the drive shaft in comparison to the trans is a needed measurement. If the engine is measured at 5.5 down and the drive shaft is 1.5 up that is 7 degrees and the U-joint will not like it for long. Then its time to look at the drive train and what can be done to help. Options are raising the trans in the back to help it but there are lots of things that can limit the rise. Another option that we used in trucks with a bunch of lift was CV joints in the front of the drive shafts. This may be the best option and allows you to run the angle in the front as needed and to point the pinion right at the back of the trans to get that u-joint angle to about 1 degree. This will drop it a good bit and lower the drive shaft in the cross member that seems to always be in the way.
