So got my adjustable rear upper arms put on tonight and set my pinion angle to were I think is right, I have never done this so I wanted u guys to take a look and c if it looked right or if it needed to be changed in which direction, I put them on and then set it to were I thought it should be then measured and made sure they were both the same length, they came out to right at 14" anyway take a look and let me know what u guys think

First question is do you have a SYE, with a CV? if so it's right.
Regular driveshaft it's not right

Pictures can be deceiving, but it looks just a tad high to me.

The test will be when you drive it, and you have no vibes while accelerating.

Sorry yea I do have a sye and tom woods, and yea ik they can and ill make sure I pay attention to when I take off for vibes, thanks for the responses so far

Like tjdave said, looks a hair too high in the pics. FYI, if you have an iPhone, there are several free angle finding apps in the AppStore

X3, your pinion angle looks too high. The pinion angle can be as low as 1-2 degrees under that of the driveshaft's angle but never even a single degree above it as yours appears to be. :)

Easy way to check it, is to get a cheap magnetic angle finder at Harbor Freight. They come with magnets that are 90 degrees apart. Stick it on the drive shaft, then stick it on a flat spot on the back of the pumpkin. I think they're less than $5.

x4, on the high side...

Ok thanks guys ill adjust it down tonight and try t find an angle finder as well to double check it

Jerry Bransford 06-21-2013 11:48 AM

I really don't believe an angle finder is all that necessary for a cv driveshaft. Most anyone can eyeball things well enough to tell when the rwo angles are the same. :)

Also, in addition to eyeballing the angle, you can definitely feel it when there are no vibes, when your angles are within spec.

Drove it this morning and didn't feel any vibes at all but that was just around town driving, I'm still going to double check everything including the angle and my jam nuts to make sure I got them tight enough cuz they were kind of a pain in the arse to get to the way they sit in the mounting brackets

98 tj sport 06-21-2013 08:14 PM

Well I checked it with the angle finder and it is actually very close, only like maybe 1degree to high so I'm going to drop it down a little bit till its about 1 degree below and go from there
