Replace that driveshaft bearing!!!

When using a poly carrier mount that locates the driveshaft to center, Which is where a new factory or new aftermarket transmission mount is most happy, you may run into a misalignment issue if you have a worn OEM trans mount, or any aftermarket inserts that raise the stock height of the transmission. Shimming with machine washers either the carrier bearing bracket or the transmission mount to align the units is important if you have a sagging transmission mount. You'll want as little misalignment in the rubber flex disc as possible. We are working on a tool that can be used with our poly carriers to get as near perfect alignment as possible. Severe misalignment (more than 10%) can cause vibrations.

My first step is to remove the trans mount insert that raises the trans 3/8" taller than stock. That should put my alignment back to being close to stock.
I am trying out the harder center bearing but I'm confident that what I am dealing with is an alignment issue from incorrectly designed aftermarket mount band aids.

2007V has a used driveshaft for sale for only $150 shipped - might make a good "core" for someone to swap out with minimal down time.

if you had let me know about it before I had you replace the center bearing I would have been a tester.... Qudos on the work though
I still have some vibration but I believe that is due to the trans position via the trans mount insert. I guess I need to do the math and shim up the carrier. Anyone know what kind of angular tolerances will lead to vibration? ex. 5 deg difference in trans output vs front half of DS.

I am picking up a truck in the next couple weeks so I'll have a spare vehicle then, if you still need someone to test I should be available to do so.
Probably not as helpful as being able to help right now, but it's the best I got.

MALLET-- We didn't have our test units in hand when you sent your shaft in. Supposedly youre able to have up to 10degrees misalignment without vibration...but that's quite a bit.
Ideally a spare driveshaft would be the ticket for being a tester. That way you don't have to have your car down, and if there are any problems you still can swap back in the stock shaft.

My bearing is bad, but so are most of my mounts, I'd be a tester but I don think I'd give good results but if your in kind of a pinch I can afford to have my car down

ok well ill put the details. $345.00 is the service fee which includes bearing, labor, heavy duty packaging and return shipping. You pay shipping to us. The bearing we use exceeds factory specs in rpm and radial load handling. We index the drive shaft prior to disassembly, there wont be any vibration unless your driveshaft was out of balance prior to shipping it to us.

Greg.... Where have I said that the driveshaft will have severe vibration after we work on it? If your driveshaft currently has severe vibration, get it balanced. We don't offer balancing services. If your shaft is free of balancing vibrations, prior to sending to us then it will be free of balancing vibrations when you get it back. If its off balance when you send to us then its gonna come back in the exact same condition.
