A few problems...

[xllkoyokollx]

Some old to the forum but they are new to me and have all happened within this week.

1. Horizontal radiator stress crack top right. (Manual Trans. so its not that big of a deal.)

2. Check Engine Light Code P0411 (anyone else had this?)

3. I am getting A lot of vibration through the trans at both the shifter and clutch pedal @ 60-65 mph. RPMs do not affect it only speed. I thought maybe I had picked up a piece of trash or something and it had gotten wrapped around the drive shaft causing it to be out of balance. But no such luck. It's worth noting that i can feel it a little from about 50 mph but it doesn't get unbearable until about 63. I feel nothing coming through the steering wheel so it must be in the drive train somewhere. (The most crucial by far.)

Any helpful info on any of these issues would be greatly appreciated...

If you don't get any replies, you could try posting your thread in the "Ask Mike" section & see if Mike has any ideas/suggestions. He's an very valuable resource here.

Haven't had any of those issues.

#1) Not sure.

#2) Found this: :link:

#3) Check CV joint on front driveshaft. I remember excessive vibration on mine when it shot grease out of the boot.

CV's are well intact. Also I would think that I would at least feel some vibration in the steering wheel if that were the case. This seems to be very localized to the trans and drive shafts. When I say the shifter vibratorates A LOT i mean it it shakes so hard and fast you can hear it moving the air and if you hold it you can feel the bones in your hand vibrating against each other. Any of you have experience with the old school brown back massagers? Its like one of those on high plus 200%. it doesn't shake anything else and I can only vagely feel it in the clutch when shifting.

If you're saying this won't happen in 2nd gear at the same RPM, it is only a speed issue, then I'd look at things that are truly going 60 mph. CVs, like cbetts pointed out. Wheel balancing. I may still check other stuff too like making sure the driveshafts u-joints are fine and the boot is not torn at the rear of the front driveshaft.

I am talking the driveshaft, not the half shafts. It has a CV joint at the transfer case.

Sorry, I guess I'm guilty of skimming posts :emb:

Ah, Okay sorry my mistake. I'll check there.

Yes, It is at speed only. I can have it in first with the tach rapping at 6k and its smooth as glass. I will check the u joints also. I also notice that the drive shaft has a tab on it similar to a weight on a wheel for balancing. Is this the case or is it something different? if it is for balancing is it like a wheel in that there could be more than one? so i may have lost one?

 

[xllkoyokollx]

ok i may have found the issue with the vibration... I check the rubber joint in front og the transfer case and there did not seem to be any leaking or tears. I check both drive shafts and both seem to have two weights on them and no apparent places where one may have once been. Then I checked the U-joints and there appears to be a small crack with new clean metal showing though on two of the four connecting points on the front portion of the rear shaft were it connect to the transfer case. I know nothing about u joints so please excuse my ignorance in regards to the terms. I snapped a pic. It was dark and the pick came out a little blurry but you can see one of the cracks i am referring too.

Lever a screwdriver blade in the joint gently and see if you can nudge the joint toward that shiny spot at all. There's always tension on the drivetrain because of the full-time 4WD so it's a little difficult to check some things. The pic is also kind of fuzzy so it's hard to tell.

Had a similar problem in my 07, 3 times... You may want to have you transfer case checked out.
