About to repair rear wheel bearing but trying to confirm that’s my issue this evening. I bought the truck just over a month ago but thought the sound was the cheaper all terrain tires the previous owner installed. I planned to get some different tires soon so didn’t let that get in the way of the sale. The only issue I’ve ever had with bearings on any gx were the fronts which would quiet down when steering either right or left depending on which side had the bad bearing. This is a constant “gerrrrring” sound after getting up to 20 mph or so. It does sound like a bad bearing but I didn’t think the rear bearing would be going out on this truck. Maybe I’m giving Toyota too much credit thinking that way on a 15 year old truck.

So I watched Timmy the toolmans youtube video on a 5th gen 4runner rear bearing replacement. Doesn’t look outside of my abilities so I guess I’ll give it a try. Any tips I should know before tackling this job? Anyone used bearings besides OEM bearings? Probably going to find some koyo bearings if I can figure out the part numbers. Saw rednexus suggested srk as an alternative in another thread. Thoughts would be appreciated.
 
I've had the SKF bearings for about a year now, they are still good. They were Japanese-made NSK bearings in a SKF box, so just as good as OEM and quite a bit cheaper. If you don't get SKF, I'd get a non-reboxed NSK, Koyo, or OEM, all of which will be made in Japan.

It's not a terrible job if you are willing to buy a 20-ton press and the Toyota bearing puller, which can set you back around $400. Also, the rear parking brake shoes/springs/cables are a nightmare to get back together correctly, but doable if you don't mind messing with each side for some time period. It should be doable in a day or less if you have all of the tools.

I have a 20 ton press I bought years ago that I use with my swagoffroad press break. Went fancy and put a pneumatic jack on it. After watching Timmy the toolmans YouTube video he recommended this one https://www.ebay.com/itm/2045075920...pid=5337589904&customid=&toolid=10001&mkevt=1
And it’s under $190 shipped. I haven’t looked at the Toyota bearing puller but will check it out.

I found passenger rear koyo bearing on partsouq for about $70 but shipping is around $50 I think. Can’t find driver side though. Looking for what you suggested now.
 
I jacked the rear of the truck up a couple hours ago and did everything I could to get some movement out of the rear wheels. Everything felt solid and I couldn’t get any rumbling when spinning them by hand just a little brake scrub. Took a ride down the road with the family and we couldn’t tell where the sound is coming from. Stumped for now.
 
How many miles on the rig? Mine were not shot at 190K when I replaced them but they definitely had signs of water intrusion and probably wouldn't have lasted more than a couple more years. If you are over 200K miles I would expect that they will need to be replaced sooner rather than later.

I’m at 148k but only had the truck for just over a month. Wish I had a set of different tires to put on to see if that’s the issue. Sounds like a bad bearing so I’m still thinking that’s my problem.

They'll need to be replaced eventually, so even if it ends up not being the issue, your time/money spent replacing them should not be in vain.

EDIT: If you do replace them, there are a few other things you'll need to get. Including rear axle seals (I go them at O'Reilly's, which had them in stock) and new C-clips (dealer-only). It is also a good time to replace your rear parking brake shoes and hardware.

Ordered one of these to help me figure it out.
