Title: Re: U-joint help Post by: Chevy1500z71 on September 13, 2008, 07:07:30 PM just take the c clips out, the new u joint will come with new ones, dont worry about bending them removing them. hit it with a big hammer on one side and the cap will come out, then do it on the other side so the other cap comes off and you will then be able to remove the u-joint.

Title: Re: U-joint help Post by: MuddFreak77 on September 15, 2008, 08:04:14 AM Hose it down with PB Blaster or Auto Tranny fluid and let it sit for a day or so if you can. Both of these will eat the rust away and make it easier.
Take the clips out of each side then using a vise or c-clamp push them out. Now you will want to use 2 sockets a big one that the cap will fit into and a smaller one that is just smaller than the cap. Use the smaller socket to push the u-joint out and into the larger one. If this does not work you might need to take the drive shaft off and use a press. Before you take the drive shaft off mark it on both ends so it goes back in the same way and is balanced.

No he means putting a mark on the drive shaft and a mark on the pinion and line them back up when reinstalling. Title: Re: U-joint help Post by: Fox17 on September 15, 2008, 03:33:59 PM i dont understand, on my truck, there are 4 bolts on each end that take the driveshaft and the 2 connectors that connect to the tranny and the diff off the truck. what is the pinion?
if i put it back wrong, would it vibrate or screw anything up? Title: Re: U-joint help Post by: LakeMaryKid on September 15, 2008, 03:40:30 PM The pinion comes out of the rear axle with a flange on the end of it. I don't know about Toyota's but on Ford's the drive shaft then bolts to the flange on the pinion with 4 12 point bolts. Normally you mark the drive shaft and pinion flange and the drive shaft then slides out of the transfer case.

Title: Re: U-joint help Post by: Chevy1500z71 on September 15, 2008, 04:37:01 PM its called a yoke, the yoke is bolted to your pinion gear on the rear end. the yoke is what the u joint is clamped on to. it sounds liek you have a solid yoke on the trans, meaning you have a slip dirveshaft. its not "adjusting", it has to slip to compensate for suspension travel. i think all that they are saying is to make sure you mark what end goes toward the front and what end is toward the back becasue of the fact that you have a solid yoke on both the trans and the rear end, you can mix them up. if you had a slip yoke on the trans (like most trucks) you couldn't mix them up.

Npe mark it so they align back up cause if you put it in 180 degrees off you might have one hell of a wobble since the shaft is not balanced. Most shafts are slip shafts and bolt or slide into the tranny/x-fer case. The Pinion end is usually held on with the saddels. mark the right side of the shaft to the right side of the yoke and tranny and also the pinion side of the shaft and the pinion. You want to make sure it goes back in EXACTLY how it came out.
