Just like any other 3rd member. If you do not know what you are doing, I would not suggest doing the job yourself. You need to have a certain amount of pre-load on the pinion at the crush sleeve. And you need to have the run out of the pinion and ring gear depth shimmed correctly to prevent noise and premature wear.

Change carrier bearing on Pontiac Torrent

You must rebuild the entire rear end, all the bearings, you can't just installed the new bearing on the ring gear carrier. This bearing replacement job requires many specialized skills and many special tools to complete the adjustments required so the rear differential won't be noisy in operation.

Mixed up rod bearing caps any soiutions

No special tools needed to tear down the D30 other than a 13mm 12 point socket to remove the hubs and a punch to remove the cross shaft pin in the carrier if you're removing the spider gears. Drain the oil and check to see if there is any metal flakes in it. Check the spider gears, ring gear and pinion for chips and/or chunks missing. IF you remove the carrier from the housing make sure that you you don't mix up the bearing caps & cups and keep them on their proper sides. My other truck had a grinding noise coming from the rear about a year ago and it ended up being the pinion that was missing 2 teeth.

Had to get the gears re-done at a shop.

The front driveshaft in my 1992 jeep cherokee laredo has a lot of play in it.i have been told the pinion bearing and seal need to be replaced.can this be done without removing the whole differential or...

I would not just replace the outer pinion bearing if there is play there. Problem is as the bearing fails, it generates fine metal debris that travels back to the inner bearing and damages that one as well. since both need to be replaced, the carrier needs to be removed and it is wise to replace both carrier side bearings. The entire job requires precision measurements and a lot of experience reading gear patterns so it's not really a job for doing at home and not even for anyone in the trade unless they have done gear setups with good results many times before.
Good news is that there are plenty of used units available in scrapyards and the unit cost end to end is less than the cost of the bearing sets. If you have a manual (chilton or haynes are fine) and a decent basic tool set, that job can be done at home with few problems. It is mandatory to match the gear ratio exactly though or you will have an immediate and catastrophic failure.(yours should have a tag on one of the cover bolts or you can count the ring gear and pinion gear teeth.) divide ring # by pinion number and that's the ratio. (example: if you get a number of 3.23 the ratio is 3.23 to 1)

Jeep wheel bearings and rear carrier bearings

As long as the diff itself was not noisy and there aren't a bunch of metal flakes floating in the lube, I suggest you pretty much leave the carrier alone. Just do the axle work, use good lube in there and be done with it.

Want to know how to install 410 gears in factory 81 cj7 rear axle

This would be a seriously long "how-to" to be answered on this forum. There are MANY tech articles written and posted on the web on how to change gears. There are specialty tools needed to ensure the correct backlash, pinion depth, etc. is achieved, the right thrust washers used, etc. The rear axle is a Dana. Any Dodge, Scout, Jeep tech forum will have this process listed step by step along with pictures. For an even better guide, pick up a repair manual for your Jeep at any auto parts store. The procedure, torque specs, pinion depth, etc. are all covered in great detail.

The simple step by step is: Remove drive shaft and diff yoke. Remove diff cover (have drain pan under it), jack up rear of vehicle, remove rear tires and brake drums, remove bolts holding axle bearing retainers in place and pull axles out far enough so they are not still in the carrier/side gears. Then mark the carrier bearing caps so you know which side they were on and which end of the bearing caps go up. (Need to put them back on in the exact orientation that they came off). Remove carrier with ring gear, remove pinion gear/shaft, replace pinion shaft/gear with 4.10 one. Replace ring gear with 4.10 one. Reinstall the reverse of removal.

There are many procedures that need to be followed during all of this such as using set up bearings to make sure the pinion depth is correct and that the gear pattern/mesh is correct. Bearings all around should be checked as long as it's apart. Best time to replace them is now if it's an 81. This is not a simple job if you have never done it. If you do not perform it correctly, the new gears will be toast very quickly. It can also be a safety hazzard.

Here are some forums.

This one is installing a locker, but same concept.

Here's a good jeep forum.

Rearend whines when i accelerate.what is it?

most likely if it whines at light throttle but stops when u get off the gas the ring and pinoin gears are noisy, if it is noisy all the time it is the carrier bearings or the pinion gear bearing.

Rear bearing

rear axle bearings I assume? Pull the diff cover, rotate the carrier so you can remove the pin from the center of the 4 spyder gears, push the axle in slightly, and remove large c clip from the carrier area. The axle will pull right out! These vehicles are hard on axle bearings. Look them all over.

Good Luck!
