dana 44 rebuild questions

[Blue_71]

i believe the K20 is ready for an axle rebuild, after having it on the road about 75 miles i have a nice roar coming from the left front (wheel bearing) and an occasional clang that sounds like its in the front end.. i do know the u-joints in it are bad. so anyways, to the questions:

is a big hub dana 44 wheel bearing any different to change then a small hub? ive done wheel bearings on a 78 dodge 1/2 ton dana 44 and a 81 chevy 1/2 ton 10 bolt, but never a pre-76 3/4 ton.

are the front axles c-clip axles? i assume they are, and ill have to take off the differential cover, and fully remove the front axles to replace the u-joints on them, correct?

is there an axle bearing at the end of the tube, like on a semi-float rear end?

thanks for any help!
