U joint write up and replacement

Postby dawgn86 » Wed Jun 26, 2013 6:56 am

I have a vibration at low speeds; I had the tires balanced and it helped some, but it is still there. I am needed new tires and I hope that fixes the problem.

I havent seen a write up on replacing the U joints on a 2wd 06 model. Has anyone done this? I have a the big C clamp ball joint press at home.

Thanks

Well I just did this last winter. It's pretty straight forward. I used a regular hammer and a socket that just fit inside the joint and a 4x4 block of wood.

Remove drive shaft by removing the 4 bolts at rear yolk, making sure to mark position of shaft to yolk so that when replaced they go back in the same position. You can use chalk, a white or "light" colored crayon or most commonly, scratch both surfaces with a flat head screw driver and a tap from the hammer.

After shaft is removed you will benefit from having a C joint clamp tool to remove the small retainers holding the joints in place, otherwise just getting the flat head screw driver in there and "popping" it out will suffice.

Lay shaft end down on the 4x4 wood and place socket inside joint then get to banging with the force of 10,000 suns, making sure not to damage your precious aluminum drive shaft though of course.

You will see art this point how they start to come out and a little "finagling" is necessary to get them all out.

Replace in reverse order, install retainer clips and don't forget to grease them if necessary.

Replace drive shaft in vehicle using the markings.

Also when you pull the drive shaft out of tranny, you will get a little fluid. No worries, it is only a little and does not effect the trans fluid level.

It's very light, easy to handle alone. You will be surprised...

If I am not mistaken, the actual shaft is made up of a composite material and the ends are aluminum.

Was the sound like a clicking sound at low rpm? Becuase mine is making this sound and this might be the fix

Cruz

mine is more like a rumble....I did the rad/transmission bypass a long time ago...trans shifts fine...fluid is fine...I changed it as well.

Im thinking tires cupped or u joints. New tires go on today and hopefully that fixes it.
