So as I posted on another thread, I have the 2" Mopar Kit Installed on my 2010 Dodge Ram 1500 4x4 Quad Cab. Looks great, but I tested it in 4WD immediately after dealer installed it and I have the wobble/shudder issue. Dealer said kit is the problem as it may be causing binding of the U-Joint on the drive shaft as it puts it at a steeper angle relative to transfer case. I called Mopar and told them what dealer said. They think thats false, but would get back to me after speaking with the engineers.

After speaking with a few other dealers, I heard there may be some wiggle room with the bolts that hold the transfer case and/or front differential in place. I don't know much, but if this is true, could it be that each ram out there has its transfer case/front differential at a slightly different angle relative to the drive shaft (from the factory), which would explain why some guys are having success with their level kits, while others like myself are not? Any mechanics on here with any input? If I get someone under there to adjust positioning of transfer case/front differential relative to drive shaft, would it cause less binding at the U-Joint and stop/reduce the shuddering?

Just a thought...

Kind of helpful link - Pinion Angles and CV Joints:

It can't possibly be the U-joint, since the position of the u-joint doesn't change with a puck lift - the diff is bolted to the frame. Neither the dealer or you seem to understand how IFS works. It's got to be the CVs

Here's a thought for you. If it is that close to the hairy edge of the CV travel, then what do you think is going to happen when the suspension unloads and travels down. Seems like you are asking for premature CV failure.

To preserve the operating range of the CV:
If you are trying to lift it, then buy a lift kit that drops the IFS. If you are trying to level it, then lower the rear.

 

Good article though if you are talking about solid axles, one of the guys in my Jeep club wrote it

 

Yeah, the guys at Mopar reminded me of that. I don't know a whole lot, forgive me. But I guess the guys who installed it didn't know much either, despite working for a Dodge dealership because they kept saying it might be the drive shaft and U-joint as well as maybe CV joints. Thanks for reply though.

 

It seems like this topic comes up at least once a week. If you do a search you'll see countless threads about the leveling kit and shuddering issues. Most people recommend having an alignment and then seeing if you have the shuddering issues. I'd start there.

 

1) oldjeep is absolutely correct...!
2) dealer dummies, and thats why you take it to a suspension specialist and install "THEIR" kits.
They do them everyday, they KNOWWWW what works

 

I had them do an alignment after install, but who knows if they messed that up. I am taking it in to another dealer for a second look.

 

I may be way off but I have some questions about the whole frame of the 1500 Rams. I don't know if this is an issue with the older framed Rams (2008 and earlier) but I'm highly suspicious of the new frame, especially with the stupid dampers that were added to the frame. What I think may be happening is frame flex that gets amplified when the geometry gets changed from stock.

I'm thinking that the engineers designed the frame with a computerized model. When they built the prototypes and started doing their qualification testing for durability, parasitic oscillations, etc, etc, they found some issues with frame flexing and oscillations so they added the dampers.

I mean, they added an aluminum hood to reduce weight but added the dampers that must weight 20 Lbs apiece? What is going on there?

 

I may be way out there but tonight I was watching Truck U and they had an episode on the Death Wobble. They where using a Super Duty Ford and they where using a WC Motorsports Super Shaker Eliminator Kit. Basically they replaced the track bar and the Ball Joints attached to them. They then replaced them with this kit. Maybe something like this is needed for the guys with the wobbling issues. Maybe the 4WD just magnifies the problem. I am no mechanic and I am not trying to be one, I just saw something that I wanted to share and see what people thought. Here is a link to the website. I do not think the internal link works but you can still see the pieces. Also you can google the kit and see a write up about it in OffRoad Magazine.
