I HAD A NEW SET OF COUNTER SHAFT BEARINGS INSTALLED NOW THE SHAFT WONT FIT I DOUBLE CHECHED I GOT THE RIGHT BEARINGS CAN ANYONE HELP THANKS

Are you talking about the drive shaft or the rear axles?

ITS THE COUNTER SHAFT IN THE ENGINE OR MAY BE CALLED Intermediate Shaft

Oh ok I have never replaced them before.

You are using alot of lube correct?

Other than that im not sure.

I FOUND MY PROBLEM AFTER THE BEARINGS ARE INSTALLED THEY HAVE TO BE LINE BORED TO THE CORRECT SIZE

Ok cool im glad you figured it out.
