I've been having some trouble with the 4Runner for a while now. On my way back from a run, my t-case started making a terrible noise. I replaced it (it had been on the list for a while), as well as the clutch since I was half way there. Then I had a clunking sound. I looked at my motor mounts and they were obviously worn. The right sat about 1/2" lower than the left and both had shiny spots on them where the metal had been rubbing. I replaced them with some burly after market ones, but the noise is still there. I'm out of things to check. Any suggestions other than looking for spots that might be rubbing? Here are the symptoms:
Clunking when the engine is under load. It appears to be speed related but I haven't gotten much above 25 mph because it's pretty bad. The noise has nothing to do with engine RPM. I don't see any obvious worn spots where things have been banging around, but I'm not sure where to look.
What do I look at now?

Have you checked all your U-joints, wheel bearings, how about your tranny? How about the timing chain gear or chain?

what about your driveline? i remember on the truck i used to hear a clunk when i had the truck loaded up. it went away when the bed was empty. maybe with your top on it squished your suspension just enough for your driveline to clunk when you hit a bump in the road or when giving it some gas. i'd check the horse collar x-member on the frame and see if there is any wear there.

The u-joints in the drivelines were fine when I pulled the t-case. The birfs and wheel bearings were new before Dusy so they should be ok. Is the only way to check them to jack up the side and see if they wobble?
How do I check the transmission? I spun it when it was on the ground, and it was smooth. I'm not sure what else to do besides that.
I'll check out the horse collar tonight, but I've never had a problem with it. I guess I could have broken a body mount that could be causing something new to rub. I didn't notice any marks on the drivelines when I had them out, but I was pretty focused on the t-case/clutch.

Have you checked your shocks and shock mounts? Check the frame for cracks.

For the longest time I had a strange noise every time I hit a bump or went around a turn.....turned out to be a spare jeep part rolling around on the floor....
I took it out and put it in my car....now my car has a weird noise, I haven't looked into it yet

Maybe the tailpipe or muffler is hitting something when the engine is under a load? I had that happen on my Jeep once. Sitting still or coasting it was fine, but under a load the engine would shift causing the exhaust to move a little and it made contact with something else.

could also be that with all the new torque your doing a wheely and the noise is what happens when you land. 😀 Let me know if that is it....

How much flex should there be in a body mount? If I use a pry bar I can definitely move mine a bit, but I don't see anything obviously broken.
I also checked the exhaust and I have plenty of space. All shocks are bolted down tightly. The horsecollar looks fine. It got dark/rainy/cold before I looked at everything, but I just don't see anything obvious.
Fortunately, Eric has volunteered to lay on a creeper under the truck while I drive fast enough to cause the clunk. It's good to have friends.

The body mounts should be solid. You should not be able to move your body with a pry bar unless Toyota is different from a Jeep. When one of my body mounts was not tight, I was getting a popping sound everytime I turned.

I'm checking it out in between rain storms! The squirrels don't like to be parked outside! I must build them a garage!

I think I've narrowed it down. Pulled the rear driveline and the noise went away. Put in my spare driveline and the noise was back. Sounds like something in the rear end. 🙁

At least that narrows it down.....have you opened it up to let out all the water?

Boooo...
Who has been doing the work on your rear axle? They were in Auburn right? Do you recommend them?

Preditor Offroad is a good place to go. They do alot of Toyota work and I wouldn't hesitate to go there. I have had them do work on my Jeep several times and have been happy. They are located off of Locksly lane in Auburn..Not sure of the number, just call information.

I'm not an expert, but, I think that I found the problem. 😯 Maybe I need a second opinion?
Someone had scratched a date of 3/?/98. Not a bad life.

Cool, wax is way cheaper than a ring and pinion. I'll even get the good stuff since I want it to hold up! I'm glad I asked for a second opinion!

😀 I was cleaning out the shed this weekend and found the 60 pinion I have laying around. Now I have 1 broken Cruiser pinion, 1 broken mini truck pinion, and 1 complete 60 pinion. I wonder if there's a lesson there?
