Car Forum / Dodge / Dodge Trucks / September 2006UPDATE 4, Bad News -- Replacing rear bearings on a Dodge pickup?
I pulled the axle and installed a new Torrington bearing and a new axle seal. I also put in a rare earth magnet on the bottom of the diff gear case. (far from gears) All of that went smoothly. Despite that, though, the noise seems to have gotten a tad better (here my senses could betray me), but it did not go away and did not become qualitatively better. Specifically, the whining noise that happens when I let go of gas, continues. i > I pulled the axle and installed a new Torrington bearing and a new > axle seal.

Did you listen to the whining noise from inside the truck with the doors shut, to offer a fair comparison to the noise you first heard? Some gear trains do whine naturally, especially those which use spur gears, but I seem to recall that all the gears I saw in your back axle were helical. The famous (and now withdrawn) Routemaster buses in the city of London had a really distinct gearbox whine, which continued pretty much all the time as I recall.

If I drive with windows open (I rarely drive with doors open:) I do not hear anything due to ambient noise. > Some gear trains do whine naturally, especially those which use spur > gears, but I seem to recall that all the gears I saw in your back axle > were helical.

Well, sure, but it started recently and seemed to be progressing. i >>> I pulled the axle and installed a new Torrington bearing and a new >>> axle seal.

If so turn up the volume and the noise will disapear. beekeep > I pulled the axle and installed a new Torrington bearing and a new > axle seal. I'm inclined to agree with Anthony that it's a pinion bearing. Chrysler products are notorious for this problem. That's why anyone that is using their truck for serious work has a Ford rear installed. The Dodge rears aren't up to the task.

If it ain't it will whine. 1/1000 of an inch makes all the difference in the world. beekeep > I pulled the axle and installed a new Torrington bearing and a new > axle seal.

Forgive me for asking what might be a stupid question, but did you fill it with grease before the test? >> I pulled the axle and installed a new Torrington bearing and a new >> axle seal. [quoted text clipped - 13 lines] > Forgive me for asking what might be a stupid question, > but did you fill it with grease before the test? Do you mean gear oil? If so, then the answer is yes. I drove 40 miles with it also, after I made my post today. i The broken clip was locking tab from the brg pre load adjuster. Did you check the back lash ?? How much back lash did you have ??? > The broken clip was locking tab from the brg pre load adjuster. Did you > check the back lash ?? How much back lash did you have ??? I just won a dial indicator on ebay, I will hopefully have it on Wednesday. I will find out and let you know what is the backlash. i > Specifically, the whining noise that happens when I let go of gas, > continues. Anytime I get whining when I let go of the gas I look at the universal joint bearings. Jack up the wheels and see if there is ANY play in the joint.

I had some rather lousy experiences with a "ford" previously. I think that for my next truck I will look into Toyota trucks. I hope that I can get a few years out of this one. i |
