Dodge Repair: Rear end, dodge ram 1500, 22in rims

Question
QUESTION: I have a 2004 dodge ram 1500 4wd 5speed manual I have a roaring noise inside the cab sounds like its comin from the rear so I put the truck on jack stands and spinned the tires and u can definently hear the roaring sound , I bought new bearings for it I haven't put them in yet , before I took the wheels off an the brake assembly to get to the four bolts on the axle , me question is , is do I need to take the rearend boil off an take the c-clip out of the rearend or is there one there or is there a tool to take the axle out , also it has 22in. Rims on it don't no if that makes a difference thank you .

ANSWER: I must start by stating that this is not the type of repair an average vehicle owner, or mechanic, should consider doing. It requires the of special tools, techniques and knowledge. Now with that said, which bearings, specifically do you intend to try and replace?

QUESTION: The part I'm replacing  is the axle bearing , what other option is there  thank you for your response

ANSWER: To gain access to to the axle bearing you will need to remove the following parts. Both wheels brake calipers and caliper mounts, brake rotors, rear differential cover, differential gear cross shaft, axle retainer c-clips, axle shafts, axle shaft seals and then the axle bearings themselves. You will still need a special bearing puller to remove the bearings however. And if the axle bearings have actually failed you will also need to replace the axle shafts. As a note, I can count on one hand the number of Chrysler Corp. axle shaft bearing I've replaced over the past 30 years, so I have to question the accuracy of your diagnosis. I would have expected that failing pinion bearings were the source of your growling noise.

QUESTION: Thats sounds like a lot of work for a part I'm not sure is the problem, how hard is it to change the pinion bearing , I do a lot of my vehicle repairs  about 95% , but nothing that is this complex thank you for your advice, but I'm on a very tight budget ,is there a way I can tell if it is the right fix

Answer
As I previously stated, this is not the type of repair that should be taken on by someone that does not have the tools or knowledge needed to do so. I understand your budgetary concerns but you should not attempt to do this yourself. The likelihood of causing greater damage is a real possibility. As far as determining which bearing has failed is a matter of locating the where the noise is loudest and the experience of knowing what you're listening to.
