I don't know if we have to remove drive shaft. It doesn't act like the front u joint is loose. What do you recommend?

[loucarter]

Oops. Sorry about that we had it wrong. It is the front u joint that is loose so would we have to take off the front drive shaft to change the front u joint? If so, do you have some instructions that we could follow and how difficult is it to change? What tools do we need?

Thanks fo much for your help.

i would check the diff fluid level and make sure there is fluid there, there is going to be a little play in the driveshaft, and the cv joints too. if you jack the front up, you can move the tires, wiggle like to make sure the bearings are good, and tie rods and ball joints.

what is making you think it's the driveshaft and or u-joint? just noise? or unbalanced?

[oxidized_black]

there are going to be little circle clips holding the u-joint on, if you're lucky it might all fall apart, or you might have to do some hammering on the centers of the u-joint itself to get it to move. heat is always good sometimes too if you're careful, just a small propane torch for plumbling....

we have the front end jacked up and when we wiggle the right front tire there is a lot of play - very loose.

thank you so much. tomorrow is a new day and we may not get to this until wed. ok we now understand how to get it apart. what about getting it back together?

[oxidized_black]

much easier !!! you'll see when the new u-joint will just slip in and clip it ...
