I'm 95% sure it's control arm bushings, or maybe sway bar bushings that are noisy on mine. It's all in the front end for me. One of these days I'll get under there with some lithium grease and see what I can make go away.
Just an idea...
When I was doing suspension work on cars in the past, I would wrap anti-roll bars with teflon tape. It isn't a permanent fix, but it would usually last for a year or more. After the tape was in there, I'd also lube it with lithium grease and that would last a long time too. I think the tape held the grease into the bushings.
I heard that a lot on this trip..I was always in the first 2-3 vehicles and it kept coming over the radio "man that 4Runner made that look easy" and I was the smallest rig every time except once. The locker is great but don't forget gearing, line choice, HC bumpers and yada that make in work together. I wish I had a crawler box..I drive a lot with both feet still trying to control my speed through obstacles. Here's one were the leader goes right and I try to make it as hard as possible and go left. I guess if I don't have the locker iit would have been harder but what's the point of spinning out when I know how to precisely apply the magic button and ease up. Makes you hungry for obstacles ...Turn down the volume....but if you listen through that squeak you can here my new exhaust...
