Valid. As far as OEM vs aftermarket, there is a price difference but never having to worry about it again is worth that difference to me.

^This. Unevenness at higher RPMs could be coil packs, which are a cheap and easy fix on the V6. You can do it in your driveway in 30 minutes, if you stop to sip a beer between coils.

Could also be a fuel pressure problem. The fuel pumps will go eventually. I did mine at something like 110k. That should cause a misfire, though.

Did you say you have no codes?

And, yes, for the love of Mike, if your shaft goes, do the Jimi fix. You don't need a carbon fiber and unicorn hair shaft, or even a rebuilt shaft (a very reasonable $400, a pleasant hour under your truck with a couple of wrenches), just some hose and zip ties and you're done. I think the latest report is a Jimi fix lasting tens of thousands of miles.

That looks great. Problem is (assuming the dealer's right) the bearing is broken/breaking so it's a bearing replacement issue, not a centering issue.


I didn't see a guarantee on the webpage but I'll call to confirm.


I'll try driving it and seeing if I hear a thumping sound under my elbow resting on the center console.
The stealership didn't suggest aftermarket, they wanted to sell me theirs.


I'll replace the coilpacks and plugs this weekend and do the Jimi fix just in case the bearing's still good and it's the rubber bearing support that's bad.

Good call. The stealer is probably wrong if you are experiencing the vibration in park. This most likely has nothing to do with your cardan shaft bearing.

When you do the Jimi fix you will see for yourself how the bearing looks/feels. It is probably fine.

Mister Quickie

What am I looking for as far as damage to the actual bearing - I realize I'll have to scrape off the old rubber per the Jimi instructions but my main concern is whether the bearing itself is damaged?

The bearing should spin freely, smoothly and quietly.

Shawn Stanford

Has anyone ever had the bearing go bad? As far as I can recall, it's always been the bearing support.

Mister Quickie

Awesome, thanks

nodoors

Yes. There have been a few. It is sealed pretty well and rather stout, but I imagine there are three cases that might contribute:

1. bad luck
2. fording deep water and giving it the ol' dunkaroo
3. driving your car too long when the bushing tears and banging it around inside the support bracket

Mister Quickie

Help - the Jimi fix can barely slide down the shaft - no way it's fitting over the bearing ... any form of grease I can use that won't compromise the rubber?

I don't want start putting stuff on there since I don't know what would compromise and what wouldn't. I could use white lithium, K-Y, motor oil ... what's best for this?

Might try some antifreeze. It is what the hose is made for. However don't cinch up the zip ties till everything is in place. If your zip ties are tight it will be really hard to get in place. I haven't done the fix myself so others may give better advice.

Mister Quickie

i've been reading to use a silicon-based grease, it it doesn't say on the label if it's silicon-based. but
i have some of this handy, would it work:

I had a similar issue getting it to slide over the bearing. What I did was get it as close as I could, loosely bolt the retaining bracket back on, sprayed some silicon type lube on the hose pieces and slowly drove around the block. It heated the rubber hose pieces up making them more pliable. It then slid right into place. I then aligned the bracket and tightened it up.

I wouldn't worry about the type of lube you use. They are simply heater hose which normally lasts 100k miles under the hood in the heat and oil and grime of an engine bay.

Out of curiosity, was your rubber bearing support damaged? Torn? Did the driveshaft easily move around if you grabbed it and tried to shake it?

Mister Quickie

I did the Jimi fix and it works but see my recommendation that I posted on the Jimi fix thread
