2006 4-Runner with driveshaft problems? - Toyota Nation Forum : Toyota Car and Truck Forums

I have a 07 4-runner with driveshaft problems. Clunking noise at stop and start. Have contacted dealership and they have done 2 temporary fixes on it but it only lasts for 4-6 months. It is still under warrenty but they have no fix for it and wont do anymore temp. fixes for it. Anyone else out there with same problem?

What exactly is their temp fix?
Have they installed a new driveshaft yet?
Have you checked online for Toyota TSB's addressing the problem?
If it's under warranty force them to fix it and don't give up. Go above the dealer's head.

BTW, it could be the slip joint in need of grease.

There temp fix is to take the driveshaft off and clean the old grease out and regrease it. It fixes it for 4-6 months. Have called the Toyota hotline and all they tell me its normal driving and the manufacturer knows about the problem but theres no fix for it. And also they will not replace the driveshaft due to they dont know if it will fix it. I have heard that they have the same problem in the 08 and 09.

locmoss,

It is the propeller shaft that tends to stick when compressed at a stop. And when you give it gas it will unstick and cause the clunk. The only fix is to clean it and regrease, as you said. My rig does it and I don't bother anymore as like you said it lasts about 6 months. I'm not going to be taking it apart at that interval just to correct an anoyance. Forgot to mention that I just lube on a regular basis.

cool will check it out, it just annoys me that they wont fix it when its under warrenty. I heard that GM grease will fix the problem but havent tryed it yet.

it may be of interest that some have also said that the clunk went away after installing a lift. myself for one, but i still lube the DS at least twice a year. some guys use 2 different kinds of grease on the 4r, the driveshaft gets one kind only.i dont know about the GM grease but alot use mobil 1 synthetic (red color) i use royal purple myself, but what ever u use , try to stick with just one & not mix em.

FSM says to use NGL-2 Lithium Complex grease with Molybdenum for the drive shaft slip joint.

The spiders (u-joints) get regular NGL-2 Lithium Complex.

Ken had a good post in 2004:

"Lithium is the base material in the grease, moly is an additive in the grease, and synthetic tells about the type of oil held in the base.

The base is the thickener. Lithium or lithium complex is probably the most popular grease base material. The base is something like a sponge. It holds oil in its pores, and the oil does the lubricating. The oil can be conventional or synthetic. Molybdenum disulfide is a dark gray powder that is very hard and very slippery. It is one possible additive to grease, and moly is excellent for slow moving, heavily loaded points...I use moly-additized grease on the sliding spline on the driveshaft.

So, grease can be lithium base, contain synthetic or conventional oil, with or without moly.

Top quality lithium base moly grease is fine everywhere. Less than top quality moly can contain abrasive particles that can damage needle, ball, or roller bearings."
