Drive shaft
 

I was able to reuse the old driveshaft by swapping out yoke. Only issue is I think it may be a tad too short.

When measuring shaft I inserted new yoke and pulled it out 3/4 of an inch. I measured 56”. The old drive shaft is 55”.

So it’s an inch too short than what I thought I’d need. The yoke is in about 3” to 3.5”.

Is this going to be a problem? I’m not gonna be racing it, but I do expect to drive it frequently and tow cars every now and then.

I think you should also tell us if your drive shaft is tapered ie 3" middle with 2 3/4" ends for example, also the material used for the piping may be thinner than what they can make you a new full length 3" one these days (3x.083), and what about the U joints are they the bigger kind, do they have the zirc fittings or not (I hear the non zirc fittings ones are stronger) I bit the bullet and dropped the $300 bucks on a new drive shaft for a piece of mind

not to offend you but was the vehicle sitting flat on the ground when you crawled under it to measure it, you don't know how many times I have seen guys measure with the truck still on jack stands

it's the towing part that concerns me

It was on sitting on all fours on a flat surface when I measured. I’m not sure on the rest of the info. I’ll have to look into it.

It’s not tapered at the ends of the drive shaft. It’s 3” shaft all the way back

Re: Drive shaft
 

cap size for both axis? measure both because you could have what's called a combo joint where two caps are big and the other two are small, ie weaker

2-3011G 3R Series Non Greasable U-Joint (CAP DIAMETER:1.125)

VS

5-1310X Non Greasable U Joint (CAP DIAMETER:1.062)

Not sure on that. I’ll have to measure. Thanks for e replies.
