carrier bearing
i have been told my carrier bearing needs replaced.
well, the guy at the shop i took my truck to, wants to charge well over $100 dollars to put it on... he said something about it needing to be pressed on. i can buy a new carrier bearing at autozone for $15-20. whats the deal?

basically its worth it unless you have a shop press. let me tell you its not fun having to wail away on it with a hammer and a large socket. its weeeeeeeell worth the 100 bucks. but thats jmho.

Just did that one. Bearing needs pressed onto splines of rear shaft. Took me 1 hour. Would take any shop press 15 minutes. That shop of yours would have lost my business right there. I used big pipe slid over the rear axle splines and hammered the bearing right on (with the aid of a little grease). No more vibrations. I'd try it yourself. Only tip would be to get an extra set of hands to mount the assembly back in one big piece (2 shafts and bearing together).
JMHO...

you can do it youself, but i learned recently from expirience that if you have to use a large pipe or socket and wail on it with a hammer, and risk damaging what your working on, its worth the money to have it done quickly by someone who knows what they are doing. that also eliminates the guess work that comes after when you wonder if you did it properly. jmho

My bad. Good catch Dr No. I guess I was just so proud of my axle bearing replacement I made it into one. I never done a carrier bearing before? So I jumped right into something I know absolutely nothing about. But I would love to know how carrier bearings are done by a non-machinist.
Sorry about that,

To answer SS's original question, the carrier bearing is the driveshaft support bearing. It is just a large sealed bearing, nothing really special about it.
The inner race is pressed onto and over a machined surface of the driveshaft, and the outer race is supported in a bracket (with a rubber bushing to cushion it) bolted to the frame.
The advice to have a machine shop do it is VERY well taken, because any work you do may easily damage the driveshaft or U-joints. All it takes is a small dent in the shaft tube to throw it out of balance.
Now, you can save some money if you will remove the driveshaft and take it to the machine shop. They will charge you big money to R&R the thing, and it is very easy to R&R.
Make sure you wrap some electricians' tape around the U-joint caps to kep them from falling off.
Hope this helps.
