Shuddering in the ?
At around 40 MPH, the area under the cab begins to "shudder". I am suspecting the U Joint. Where the drive shaft slides into the tailpeice, it feels like a little to much play, but how much is to much? Could it be The motor mounts? Thanks much for any info! Joe

Re: Shuddering in the ?
Are you sure is not just one of your tires out of balance?

Re: Shuddering in the ?
If it's a tire it would be a rear one because you are felling it in the cab, a front one would be in the steering.

Re: Shuddering in the ?
I'm sure Its not the tires. The "shuddering" Is intermittent. I too believe its probably the U joints and am in the process of replacing them. I will Post when I get them in and do a road test. Thanks much to both of you for the info. Joe

Re: Shuddering in the ?
I vote for Ujoints. I had a similar condition in my truck recently. I checked for play in the joints, but didn't have any.
For giggles I pulled the drive shaft and found one of the three caps in my rear joint had no grease, and subsequently the bearings were dust. |
