Driveline stuff

All the U-joints on both shafts appear fine and I've greased them regularly. However, I can feel a little play in the slip yolk on the front shaft.

- Long story short, I'm just going to replace both shafts /joints entirely.... start from scratch. I purchased this truck with 365k and when Rawze and I looked at the ECM info form the old engine, it looked like the truck had been beat on pretty hard for much of that time. I've since put another 100k mi on her and although as easy as I can be, still can't account for the previous abuse it withstood.

Dropping and replacing both shafts with new in one morning makes more sense from a financial point of view. Even if it costs more initially, the lost revenue of having someone repair what I have would cost much more overall. Plus, it will all be fresh and I'll (hopefully) know what I have.

Could anyone recommend a good driveline shop in the lower Ms/La area? Im within about 20 miles of the Slidell area if anyone is familiar with that location.

Are you sure your shafts are bad? I paid 250 to have a shop balance and install my joints and carrier bearing into my shafts. Parts cost about $380. They even marked it for me real well so it was easy to put back in. Running good, haggi found steer tires were bad. But bad vibrations can cause other stuff to break from wobbling and stuff so good to get to it!
I bought a tiger tool to remove them and made it pretty easy. If mark it real well with a paint pen.
And don’t drop the caps so not lose any needle bearings.
