They're a press fit. Although not that close if it's rusted on there it could give you some trouble. You could try heating it. Or if you have a press. Or take it to a machine shop.

Re: 72 Chevy C-10,LWB Drive line help, Please
to take the carrier bearing off, you need to take the center u-joint off from the clips then there is a bolt behind that you should pull and slide the yolk out then the bearing will slip off. I have never had one pressed on. but It might be pressed in there but I would try to pull the u-joint and yolk off first and see what you get into. easier then going to a machine shop and paying when you really dont need too spend the money for something simple

I have done 3 in the past 6 weeks and every single on has been pressed on. Pull them off with a puller, and every new one did nto slide right on the shaft you had to press it on... which is the only way the bearing is going to work. So they have to be a press fit

Re: 72 Chevy C-10,LWB Drive line help, Please
Doing mine right now. easist way IMO is drop the 4 bolts holding carrier bearing on frame. Seperate the back shaft from front by sliding the yokes apart. Pull front shaft out of tranny. Have pan ready for fluid. You have to seperate 2 halves of housing. Then press or pull slinger/ bearing retainer off then press bearing off the shaft. It helps to soak it with some CRS or rust penetrant over night. They are pressed on At least for a 68 C20. Also, where can you buy a new Carrier bearing exactly like the old. NAPA has some strange looking crap that requires you make a spacer for the mount.

Re: 72 Chevy C-10,LWB Drive line help, Please
Piece of cake! I soaked it in Kroil over night and it came apart with just a little persuasion and 1/2 NF bolt and thrust washer "presses" it on the last 1/4" or so. Thanks for the help all of you! Brakes are next,I get them tomorrow.

Re: 72 Chevy C-10,LWB Drive line help, Please
Make sure you mark the two shafts so they go back together the same as they were. I had a vibration problem when I put them together 180 degrees out. I didn't think it would matter, but my new bearing only lasted about 6 months. It's been 4 years on my third bearing, and all's happy!
Good Luck!

Is the bolt that holds yolk on Reverse thread??? I am having a hell of a time breaking mine loose, I actually broke my vice trying to get it loose.

Re: 72 Chevy C-10,LWB Drive line help, Please
all carrier bearings are a press fit, if the old one slides off, the weld in stub needs to be replaced. also if the bolt on yoke has any play in it, both the yoke and stub need to be replaced.
dont put your driveshaft in a vice, dont beat on your driveshaft in a vice, dont crush your yoke when installing or removing ujoints. if i had to remove a carrier bearing at home i would cut it off, as it is typical for them to be quite stubborn to remove. even when using tools designed for driveline work it is possible to damage a shaft by the forces required to remove a carrier bearing in 1 piece.

Re: 72 Chevy C-10,LWB Drive line help, Please
When my carrier bearing went bad, it also took out the dust shield on the end of the drive shaft. Does anyone know where you can get a new dust shield?
I believe that it was welded to the end of the drive shaft. To take mine apart, I took both of the universals out and I removed the bolt from the end and then I put a pry bar in both ends and I chained it to a tree and I used a come along to pull the yoke off the end of the drive shaft. Because the carrier bearing was completely gone, all I had to do was take the remaining part of the bearing off and slide on the new bearing. But because the dust shield was gone, it didn't last very long. $12 is cheap, I think I paid $40 for one 25 years ago. |

Re: 72 Chevy C-10,LWB Drive line help, Please
carrier bearings will last a long time when the shafts are in good condition and ballanced. even the cheap ones.
dust shields are completely not needed. i spend about 40 hours a week building and repairing driveshafts for anything from hydrostatic kohler lawnmowers to ride the ducks amphibious vehicles. ![]()

Re: 72 Chevy C-10,LWB Drive line help, Please
before you install the bearing weld the edges of the top flange to the lower. it is just held by spot welds. i had 2 break there before i welded mine and they were spicer bearings.

http://www.iedls.com/bearings.html If you want a heavy duty bearing or do not want to do the job again I recommend one like this.
