Driveshaft length tolerances +/-?

[Righty Tighty]

Well folks, feel free to say you told me so. I thought I had found a drive shaft that was the correct length according to the charts I found, so I installed it and BAM!! Three full inches too SHORT!!!! Don't ask how or why, but it was.

Luckily I still had my old shaft, so I measured and had it cut by the driveline shop. I know, I know. You said to measure and I didn’t.

Lesson learned.

Looks like you cut a little bit off both ends and it was STILL too short..

glad you got it sorted out...so how long was the one you bought and how long is the cut one?

short enough not to bottom out and long enough not to pull out.

That’s what SHE said...

The one I bought was 49.625 and the cut length I ended up with is 52.525(ish). I don’t remember the exact cut length, but I have it written down somewhere.

Also, the drive shaft I was already running and had cut is a 3” diameter shaft, while the one I bought was 2.75” diameter. I don’t know if it makes that much of a difference, but I would think a larger diameter would provide more strength, no?
