wheel bearings

I plan to do the brake pads, rotors, and wheel bearings when I do the lift on my jeep, but, I have a few questions:

1. is there one front hub assembly brand that is preferred? timken, mopar, etc?

2. Is the rear an assembly too, or is it sometime of actual bearing that needs replaced? any instructions or write ups on this?

First answer, factory or a high quality bearings. Second answer, unless the axle seals or the bearing have play in them, leave it alone.

Axle seals are leaking or the bearings have play in them. It what I wanted to say.

For the front, I used a set of hubs (unit bearings) from detroitaxle.com. Don't know about a general preference but most unit bearings are probably made in China. It'll be at least a few more years (if ever) before Trump's policies get that trend turned around.

The rear bearings are pressed on to the axle shafts. I just upgraded to cromoly shafts with new bearings already installed (Nitro Gear & Axle).

Last time I checked a couple years ago, the OEM and aftermarket JK front unit bearings were made by ILJIN in Korea.
The name on the box made no difference.

Don't know if that has changed since then.

I just use NAPA premium unit bearings on my Jeep. Always in stock and decent price last time I bought them.

ok ill just price the best deal I can find on the fronts. With the rears, does one shaft company stand out? Ive read where revolution has a lifetime warranty on the US made versions. Do they all come pre assembled with shafts and bearings?

No you'll find bare shafts too.

I twisted my stock rears at the spline a while back.

$ was tight at the time, I did a little research and went with “ten factory” assemblies.

Reasonable prices, decent warranty, good reputation.
I didn’t find any bad info that was backed up by facts/proof.
