    Question pictchin a diff?

    I installed a SYE kit and got a cv driveshaft installed awhile back and even tho i have a much smoother ride i can still feel some vibrations. ive been looking around thinkin i need another driveshaft and it said to pitch the diff to help with the angle. has anyone done this and could provide some info on how to do it. thanks

    You have a couple of options to rotate the diff up. You can install axle shims. The safer way it to cut off the spring pads/coil holder, turn the pinion, and reweld them back on. Here's a more detailed site to help answer your question - Tom Woods driveshafts http://www.4xshaft.com/index.html

    when I put the lift kit on my jeep, everywhere I looke dsaid I would not need an SYE or shims for the lift I was doing. However, after having the lift installed The vibrations where fierce, so I ended up adding axle shims. Very easy to install. takes less than 20 minutes. Also, you got to remember, If it's lifted, your never going to rid of all the vibrations.

    From the picture in your profile looks like you have a TJ. Do you have adjustable control arms? If not look into a set of upper and lower adjustable control arms. With them installed you will be able to fine tune the angles. Should cure most of the vibs.

    You should only need upper adjustable cont. arms. lenghten to rotate pinion angle up.......get some for front also.(only uppers) Priceee but recommend JKS they are bullet-proof plus you can get all matching control arms later.............$0.02

    JKS, RockKrawler, or even make your own. Also keep a look out on craigslist or forums for someone upgrading, get them cheap.
