Clunking from rear - Page 2 - TundraTalk.net

AXLES ETC · 08-01-2008, 05:07 PM

Never gonna be able to drill into a ujoint, There case hardened, Unless you have the cheapest Chineses ujoints money can buy, then You'll be able to. All the driveshafts of the Newer body Tundra should be servicable with fittings, It's the first time Toyota ever used spicer products on the Tundra, The first gereration Tundras used Japenese design shafts which I think were much better than Spicer anyways. Grease isnt gonna stop the clunking, Thats means it's behyond that, The joints probably bad.

I work at a driveline company, we make driveshafts and axles here, Thats how I Know this info. Most of the time when the rear u-joint goes bad it's because of an angle problem.

There have been people that have had their drive lines replaced with no change in the clunking. I dont believe it's a u-joint. I think it's a dimensional tolerance problem with the drive shaft.

That link I posted, they were talking about the yoke not the u-joint.

The only yoke you can grease is a stub shaft yoke, Tube yokes dont do anything but hold the ujoint in palce, Dont no what there tal;king about when they say grease the yoke??? Makes no sense. Also, Maybe the driveshafts are not being balanced properly from the factory ...

They are talking about the yoke that meshes up with the splines on the output shaft of the tranny. I had an earlier post on this thread on what I did to my wifes Tahoe. It worked. The clunk feels like it comes from the rear end but it actually happens at the tranny. I have seen these yokes with grease zerks on them. The dimensional problem I spoke of is I think maybe the shafts are a bit short. They still mesh up but they allow to much play.

I think I'm wrong about this. Looks like there is no yoke that slides in the end of the tranny. Could not tell how it is connected, bolted or a slip yoke. Theres a cover over it. Should have looked before I leaped!

Could it be this? Take a look ,this is a Toyota Service Bulletin.Hope this helps 07-08 Owners.

Very interesting ! It sure pays to be alert and up to date on factory issues. Thanks and have a great weekend.

Yea, The tundra I have has a 4 bolt flange on the front by the trannie. Pretty comon on Fords But most have a slipe shaft that slides onto the output shaft of the trans. And thanks for the info 1txtundra, Thats good info on that bulletin.
