Midshaft bearing Problem - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Mine is bad. I got the bracket off and dropped the back shaft. I cant get it to seperate at the midshaft. It keeps wanting to slide out of the yoke. Is this because in has been pressed in somehow or am i I not tugging enough. The replacement bearing I got makes it look like both sides just slide in. Any input?

I did one long ago,so take this with a grain of salt.IIRC the yoke on the rear half slipped into the front half,then had a bolt thru the center holding it in.I think I had to remove the u-joint to remove the bolt so I could seperate the two shafts.

I just did this job last weekend and that is correct. you have to pull the entire drive shaft assembly and remove the center u-joint. There is a bolt that holds the "ears" for the u-joint to the front driveshaft. That is the only way to remove the middle carrier bearing.

I do this on a weekly basis. Mark the shaft! So you can line up all of the piees of the driveshaft so it might have a chance of being ballanced. Pull ujoint, pull bolt, remove bolt on yoke remove carrier bearing. Please don't put shaft in a vice, they bend easily.

so why did the carrier bearing go bad? Age, ballance, mechanical failure?

good luck
