u-joints, a common simple repair that often gets complicated.

When I worked at a shop (12 years ago) I had the use of a large vise and a shop press, but at home I can still manage using sockets and a hammer, especially on aluminum yokes where you don't need as much force to get the old ones out.

It can be done without removing the C-beam but I assure you, from personal experience, it is a huge pain in the ***.

sure is...

remove the C beam...takes about 20min...makes life alot easier!

also, install the c-beam plates or you'll find yourself cussing like a sailor trying to hold the top nuts still while tightening everything down...

i made my own when i sandwiched my entire c-beam in 3/16" steel for the BBC project. it made reassembly so much easier

Thanks for all the help guys! i think im gonna wait on the main shaft. the half shafts are more prone to going out right? or would you recomend replacing all 6 at once?

they're cheap enough i'd just do all 6 at once...no sense in getting under the car twice for the same job...

1) the trans is coupled to the rear diff with the C-beam so the angle it operates at is nearly straight most of the time unlike a conventional solid axle rear so they should last longer than a regular car.

2) the half shafts have a 3:1 torque multiplication through the ring and pinion (depending on exact gear ratio) and operate through a wider range of angle so they would likely fail much sooner.
