Bad Vibration at 55 with trans Locked
Hey Guy's well here we go again it seems that I have some sort of issue with either the drive shaft,universal's or the converter?? Out of no where while getting on the Highway yesterday I proceded as normal to accelerate up tpo speed and as soon as the trans locked up in OD and hit approx. 55 the truck began to vibrate? It seems to go away past 65. Anyone have this issue? Tires look good? What do I check??
Thanks

Feeling vibration from steering wheel only at certain speed?
Usually this is because of defective or unbalanced tires. A defective balanced tire will do the same thing.
I would rotate the tires and see what will happen.
Just my two cents.

Nah just did that besides it came on very sudden.I believe it might be the rear u-joint because I thought that heard that tell tail click whe I backed up after getting the mail. Now the question is do I replace all of the joints or just the bad one? The truck has 61k on it....

Change your u-joints. My rear joint went bad and I swore it was something in my front end... steering wheel vibes and such. Does it go away if you let off of the gas pedal? If so, I'd say with almost 100% certainty its a joint.

I got mine at my driveshaft guys shop. Neapco or Spicer. Get the greaseable ones. You can get em' online also. Make sure you get the correct ones. My driveshaft was slightly bent also but a good driveshaft guy can fix that.

Just did the rear U-joint on the rear DS this afternoon. This one has the plastic inserts instead of spring clips but the Spicer 5-801X with outside spring clips work. I had purchased U-joints a while ago as a PM item and all of a sudden.................well after I removed the helper springs and swapped the spacers, I got this vibration. It was a high frequency vibe, not a tire balance issue. TMALSS, I had the Spicer 5-801X joints for the rear DS and was wondering if I had the correct parts.......I did, but it took a trip under the truck with my caliper. After wrestling the rear U-joint in and breaking my bench vice in the process, I called it a day and reinstalled the DS. One of the caps on the rear joint was rusty and all the bearings were destroyed. As we all know, you have to drop the shaft to really know if the U-joint is good. BTW, the two piece driveshaft is one heavy piece of pipe
The 2 sizes of U-joints are with 1 3/16" end caps and 1 3/8" end caps.
Spicer 5-801X are the 1 3/16"
Spicer 5-803X are the 1 3/8"
