Need detailed manual or assistance in replacing left rear axle seal and bearing on 2005 GMC Sierra pickup with 5.3L engine and a 324 rear end

not very much info. 1/2 ton? 2wd? If it is a standard pickup there are "C" clips that hold the axles in. You will have to remove the 3rd member cover and remove the clip. This is after you have removed the wheel and brake drum. The axle will slide out and the bearing will remain in the axle housing.Messy job. Take it to your mechanic.

not enough detail for what end the leak is at. Front sounds strange for a pickup unless 4 wheel drive and then if the style is open shaft behind the brake rotor this would require dissemble of a few more things. If from the rear,which is the common repair, this is from a worn axle bearing on the axle shaft,which causes wear to the rear axle seal either located on the shaft before the bearing to the outside. Or the second option can be a axle seal located in the end of the axle housing. when you remove the axle shaft you would be looking at the end of the housing tube and see this seal. On older models ( My younger days ) they would also install one on the inner side of the housing next to the Gear Unit in the center of housing, ( also known as the PIG Unit ).need further info....

Yes,the axle has to come out.Which means the rear end cover has to be removed.If your not familiar with this process you should not attempt it on your own or you could end up with bigger head aches.Hope this heaps.Good luck.

SEAL COULD BE LEAKING CAUSE YOU DIDNT LUBRICATE THE SEAL LIPS WITH PETROLEUM JELLY TO HELP THE THE SEAL LIP SEAL OR YOU DAMAGE THE SEAL WHILE DRIVING IT IN.AXLE FLANGE NUTS TORQUE IS 58 FT LBS THE AXLE HUB NUT TORQUE IS 177 FT LBS.

if the seal (s) is leaking you may have a bad bearing... to change.. remove the rear end cover, reach in pull the c clip on left or rt side. pull the axel out the side, use bearing puller to pull the old bearing, install new replacement bearing seal, put in axel, replace clip, reinstall rear cover, sealing properly, fill with rear gear lube to level of fill hole. get a chiltons manual for pictures and more detailed help.

Depends on what kind of axle you have. Is it a semi-floating axle, or a full-floating type?

is your clutch pedal spongy if it is a hydraulic clutch there will be a small resivoir on the fire wall next to the brake master cylinder,if so check the fluid level,the noise your describing sounds like drive shaft u-joints,or cv axle drive shafts in front if its 4 wheel drive,block the wheels and put the truck in neutral,to release any tension on the drive shaft,go underneath,grab the driveshaft a foot behind the transmission,and push up an pull down on it while observing the u-joint in front of it if there is any looseness or play it is damaged,any movement up and down or left and right requires replacement,do the same to the other end at the rear axle,the rear axle u-joint is the most common failure,but check them both,

yes this is normal wear, if you have aftermaket wheels and tires the wear will be quicker do to more stress on the bearing, for the rear seal no u do not have to remove the cover if you jack up the side that has the bad seal you dont even have to drain the fluid. the outer bolts hold the axle in. there is no c clip inside the axle to remove

jack & support vehicle. remove rear axle cover drain fluid, removeleft rear tire drum/rotor brakes, remove bolt in axle housing that holds the 3/4 inch pin in place pull pin , push left axle shaft inwards and remove c clip from inside axle case,slide out axle shaft,remove seal,remove bearing and install in revers

Not extremely hard just need the right tools for it and a manual.
