Drive Line

hey guys, i still have a clunking/squeeking in my driveline. i took it in and he said i need to rebuild it or buy a new shaft. The weird thing is he said that i have CV joints on both sides but i dont think this can be right becuase theres no grease boot and it looks like u joints. do they even make cv shafts for the rear on broncos?

i know a new drive shaft is pricy with labor and all so is it better to have the joint rebuilt or just buy a new shaft all together?

thanks- brenden

Yes, you have CV joints ....they're great !
Get them done or do yourself.
The CV end has 2 u-joints & can be tricky, but do-able.
You'll feel the difference.

so are u saying that one end of the shaft has a cv joint? if its a cv why isnt there a grease boot?

Because it's not a Transaxle........it's still a "Constant Velocity Joint".

CV stands for constant velocity, it's a term that is used for several styles of driveline joints.

The Bronco uses a "double cardan" u-joint system, commonly referred to as a CV joint.
The double cardan consists of a yoke, a u-joint, a centre yoke (h shaped) and a centering socket yoke w/ pivot ball (inside the centre yoke) which in turn connect to both another u-joint and finally to the drive shaft... kinda hard to explain. here's a pic from Chilton. Because this system uses u-joints there is no need for boots.
