I am new to this thread, so first let me say thanks for all of the great advice I found on this website. I have an Fj40 that has been sitting for 5 years due to an overheating problem after a 350 installation. I took care of that issue thanks to these forums.
Here is my new problem. I can drive in 2 wheel drive with no problems. Yesterday, I wanted to test out the 4 wheel drive since it has been awhile. After locking the hubs and shifting to 4 wheel drive, I started driving. When I hit about 20 miles per hour and either let off the gas or shifted, I would get this grinding noise from somewhere in the front end. If I step on the gas, the noise goes away.
Today, changed the front differential gear oil to make sure it was full and to make sure there were no metal shavings. Everything looked good, but the noise is still there. I unlocked the hubs, kept it in 4 wheel drive, and I still got the noise. It is a pretty loud grinding noise. Any ideas?
