Vibration/grinding feeling in gas pedal 35-50mph ??

Good news. I drove an hour an a half today and picked up the used drive shaft. Drove home greased up the beat up looking ujoints probably original and cardon joint and slip yoke.

And installed it vibration is FIXED. Just shows even if you pay a drive line shop to rebuild your drive shaft it dont mean squat. Also when I dropped my original drive shaft to be rebuilt told owner just replace everything 1 and done so I dont have to worry about it at all. This whole time scratching my head it was a bad rebuild from Pete's welding. Damn

Not all driveshaft shops are equal, I learner that with my Chevy pickup. I had a bad vibration from the rear end, took to shaft shop to replace all u joint and balance and only helped didn't eliminate vibration. So took to another driveshaft shop and had them balance it, still had vibration. Talked to some local 4x4 guys who recommended this little tiny hole in the wall shop to balance it and when I took it to him he looked at all the weights on it from previous balances said what the he'll were these people doing removed all the weights started over balanced it with only a single weight needed and it was fixed. He was also the cheapest.

So I've recently noticed a vibration feeling coming from what seems like the front end. I feel it in the gas peddle and front floor board (passenger and drivers said) when accelerating between 25-30mph. I was under the truck looking at all the wheels to see if anything was rubbing. It seems less as I speed up. Like it was hitting every tread slowly then running smoother when speed increased. Hence I thought something was rubbing. Is this the same thing?

sounds similar to the issue i’m having now, but i believe i’ve narrowed it down to the u joints. glad to hear you got it fixed.
