Vibration 2.0 diesel 50 mph - 2006 Jaguar S-Type

Hi, you could check your engine mounts.

Sounds liike a ring and pinion on rear differential. U can pull the cover off and check this or another thing would be to check your u-joints.

Harmonic balancer.

1= Universal joints or yokes, or drivesshaft splines are worn.
2) driveshaft is bent
3)engine or transmission, or center driveshaft nager might be loose or worn.
God bless you

sounds like a bent wheel rim

check for problem drive line "U" joints or cv joints

Check for carrier bearing problem

50-60 mph vibration may be as simple as tires being out of balance or an unevenly worn tire(s)

Welcome to fixya the best thing to do is check the rims for imperfections and slight bents that causes the vibrations at that speed go to www.collisionrepairadvice.com to get a wheel repair company to look at.

I have the same thing but mine is between 45-50 mph. I read about this a while back in a magazine for people that pull campers, the problem exists in all vehicles although its not as noticeable in every thing you ride in. There is a certain "point" at which your speed and engine speed reach, that causes a phenomonon that causes a vibration. Engineers relate it to "harmonics" which is a similar issue but in the electronic field of study. There is nothing you can do for it, and it varies from unnoticeable in some vehicles to driving you insane in my 1989 Mazda B2200. I had an '89 Ford F-150 that did it at 35 mph and a 2001 Dodge Diesel that did it at 45 mph, but those were the only three vehicles I've ever driven and noticed it.
