After the original center support bearing wore out, I replaced it with the best one Napa had. Now only after about 500 miles the rubber is wore out. I double checked everything. All U-joints are new, the splines are great and not twisted. I even replaced the tranny mount 500 miles ago to. I did the alignment correct when I replaced the bearing. My question is I have searched on here and seen about a big international bearing that would work, does anyone have a part number?
 
I prefer large single piece drive shafts...carrier bearings are for the birds!
 
I had one installed at the local drive shaft shop. I just had to make a bracket to hold it.
 
Are you getting lots of driveline slop? Is this the reason your replacing it or?
 
I have no slop I just think it is axle wrap and the heavy loads I pull with it. I don't sled pull with it so I never did make bars for it. I might just run out to the semi shop and have them make me a one piece. I think I have all the stuff lying around. Just have them weld the yokes and balance it.
 
Well thats kinda what I was referring to. I have the same issue with my 2wd. Im hoping that when i can make some bars for it, it will help.
 
Would a one piece solve alot of my issues you thing? For just a street driven 2wd?
 
Just a heads up, depending on the length of the one piece you will be RPM limited. My shaft is 73.625" and I am limited to 2k shaft RPM, which is 70 MPH.
 
doesnt sound to good for the race track sounds like your limited after you install it. daily beater then sounds great
 
I checked it in a lathe with a dial indicator and it was good. I just might take it to a shop and maybe they see something I don't and I might double check the rearend for slop. To answer the other questions any driveshaft shop can make you a one piece shaft. Some don't like to make the long ones because of balance issues. etc.
