if its the hub it self then its a axle change.
You don't, you replace it.
Trying to fix a cv axle half shaft your self is difficult. Replace it with a rebuilt or new half shaft. The parts to repair yours would cost you more than a complete replacement does.
Depending on what made it go crooked : If it is wear you can replace bushings or bearings (might have to replace the axle shaft to.) that should fix it. If it has a bent axle shaft then you can take the wheel off and take a pipe put it over the end of the shaft and bend it back to straight. If you mean the toe in or out you can unbolt the swivels on the pull arms and adjust them that way. Hope this helps.
It depends on how it is bent. If it is just the flitting you can use a bar and a hammer. If it is the shaft you might be able to bend it back with a bar. If not you will have to replace it with new or used parts.
The rear, or tail shaft, of a transmission has a seal around the output shaft. The drive shaft will have to be removed and the seal replaced.
the shaft will, but the axle clips might not, but that is a very cheap fix, the clips are around 15 for a set
Inner or outer front? I do a lot of repairs myself, engine rebuild, transmission swaps, there are 3 things on a 4x4 I will not open up and fix.. front axle, transfer case, rear axle. I hate the smell of burnt gl5. I hate putting it back together and having a seal tear while pushing the shaft thru it.. unless you are talking about the rear pumpkin seal.. 10-15 bolts new gasket and a little permatex.. So for my answer How would I replace the rear axle seals I would take it to a shop and pay them unless I could find the exact axle at a junk yard for the cost of half of shops fee.
check the tailgate Check the ubolts on the axle, I had a rattle in the rear, the u bolts were loose on the drivers side of the rear axle i had a rear end noise as well. turned out my spare tire was loose. might want to check that out. My rattle was a broken leaf spring
Behind the passenger rear axle by the fuel tank very easy fix
It is located on the rear of the transmission, drivers side. 5 minute fix...
Pinion seal: Remove the drive shaft from the yoke. Pull the pinion yoke off the pinion shaft. Remove the old seal and hammer on a new one. Seal is about 10 bucks. Re-assemble Rear cover: Remove the cover bolts. Put a pan under the rear end and pry the cover off. Clean and re-silicone the cover Re-assemble. WARNING!!!!! Don't let the rear end run dry, will cost you pinion bearings in a very short time.
