Can't figure this out!! I will GIVE 50$ to who ever can help me out!!

Why don't you have some one drive next to you while the shake happens on both driver and pass side of truck.
If might be able to see something.

Just sayin.

 

Had A friend that would get a vibration at 55mph. The faster he went the more the vibration would turn into a wheel hop. Turn out it was a bad shock. Food for thought.

 

Idk !! It's too early in the morning I can't do the math for kph to mph

 

Yeah I didn't mention it actually but I have that egg shapped tire feel at lower speeds aswell but my vibration doesn't go away if I go faster.

Still no solution.

 

There are other questions will still need your response to, a few posts back.

 

There is a TSB for a torque converter lock up shudder from 3rd to 4th that causes a "rumble strip" feeling while driving. All that is done is a Econ reflash to prevent incorrect learning values. Only thing is it's for a 4banger.

 

There is also a newly designed torque converter for the V6. Due to a shudder issue and something else. It is also more robust than the previous version.

 

I have this exact same issue on my truck. The dealer initially blew me off saying it was my tires but I finally convinced the service manager to take a ride with me then pop on some stock wheels and go for another ride to show it was still there. I would have left the truck there today but I need it tomorrow. Anyway, they finally acknowledged the problem and I bring the truck back in on Monday so post an update with what they find.

 

Good to hear that they are checking it out. And yes please post on here what they find, still no solution to mine.

 

I got a call from the dealer today and they ordered a new driveshaft to be installed tomorrow. The service writer didn't know what they found wrong with it but I'm hoping that will fix the issue. I'll post another update tomorrow when I get the truck back or hear from them that it didn't fix it.

 

Right on! I had mine checked over and re-balanced, unfortunately that wasn't my problem.

 

Which one of the ujoints haven't been changed?

 

What a buzz kill you are

 

Cool AND original. You must have to fend the girls off with a stick when they see you have stock tires and wheels too

 

I had a Jeep where a Curb jumped right in front of me, that developed that kind of humming/vibration after 60mph. Replaced Front Driveshaft with a brand new one and would still do it. However when I took the Front Drive Shaft off, the humming/vibration would go away. So it was something to do with the Front Differential that got slightly out of whack... Visually it looked fine. Just when going over 60 is when you could hear/feel it.

Had to sell Jeep shortly after so I wasn't able to pinpoint actual culprit... Hope you find it...

 

Parts are on order so I picked up my truck today, this is what's on the invoice.

 

Is the problem on yours fixed?

 

I'll let you know once the part comes in and I get the work done.
