i just replaced the whole shaft on mine now i get vibration some times at 90-100km like the truck shakes but no vibration in the steering wheel. i asked my uncle if i had to mark it and he said no as it was a brand new shaft. any ideas?

 

An out-of-balance shaft won't cause a shake. It will cause a vibration more like a low-frequency hum. If you feel something shaking, but not in the steering wheel, you may have a wheel that's out of balance, especially on the rear.

 

Idk, all I knew is that I was surprised they replaced my cv as it was shattered that was due to heat and stress. Obviously its from the lack of grease, I don't Think I added enough. I added much more grease to the joint. Also, its easie to maneuver the rubber boot onto the driveshaft if you apply grease to the shaft.

 

Could also be a pinion bearing, which was my problem. Dodge replaced the whole front differential. Before you rebuild the drive shaft, check with O'Reillys, Kragen, etc.. I bought a new front shaft for my IFS Chevy for 1/3 of the cost of rebuilding.

 

New driveshaft is still the most expensive route.

 

When that CV joint went out on mine I just replaced it with a double u-joint shaft. Never have to mess with it again.

 

That's probably the best way to go.
If this new CV joint that I'm putting in doesn't last, that's what I'll replace it with.

 

Update. Got new CV joint installed, rumble noise gone.

 

Glad to hear your issue is now gone.

It's good to see the final resolve.

 

yah mine rumbled at what seemed to be 3rd and 4th gear untill untill I iether gunned it or slowed down. once the new drive shaft was in it was gone wierd.
