Slip yoke on a TH400
I am at the point of putting in a driveshaft on my SWB project truck, and was wondering how much "slip" is needed on a TH400 mated to a 402? I have a factory 2 piece driveshaft from a SWB parts chassis that I mocked up (This is the correct TH400 yoke). I measured and there is 1 3/4" before the yoke bottoms out on the tailshaft housing. Here is a pic to illustrate. Yep, I plan on replacing the u-joints too Thank you in advance.

Re: Slip yoke on a TH400
If you are using a two piece shaft, the front section stays static and is located by the carrier bearing. The back section slides on the spline joint mating the two pieces as the axle moves up and down. Therefore, I don't think you need much travel for your front (transmission) yoke. I had about 3/8" on my 200 4R install and it seems to be fine. Someone else I'm sure will pipe in.

Re: Slip yoke on a TH400
I think they say 3/4 to 1 inch of travel, however I doubt 1 1/4" would be a problem.

Re: Slip yoke on a TH400
Well, it looks like I am good to go then
The carrier bearing has some adjustability as to where it mounts on the x-member. I had it in the "middle" in this pic. I can slide it forward a small amount, and that would give me exactly one inch of travel. The slip yoke has no wear on the outside and it drove great with no driveline vibrations when it was in use a few months ago on my LWB truck. Thanks for the input guys!
