if the t-case comes out of a auto truck will it be a direct replacement or not???

Thanks for the info in advance

 

no one has done this swap?

 

I think there are subtle driveshaft length differences, other than that I think it is a direct bolt in.

Both of mine are DHDs so I have no experience with a DLD.

 

for some reason i think that the input gear has a different number of teeth. i k when i did my tranny swap from auto to man, i had to change out the input gear from the 27 spline to a 29 spline. other than that i cant remember what the differences are. ive got a parts book at home and can take a look at it and get back on here tomorrow on the differences.

 

Autos should have a 23 spline for both DHD/DLD, Manuals should be 29 for both.

 

thats right pat. i forgot the exact spline count on the auto/ man shafts. do you know the difference in the dhd/dld t-cases. just curious for my own knowledge. i forget.

 

I think the tailhousing on the DHD is about an inch longer.

 

so I was thinking of switching the tailhousings or swaping the youks, I did call the local ******* and asked they said the only diff. is the internal things for what that is worth.
Thanks for al the info

Pat is there any way could measure your t-case from front to the center of the u-joint cap too see how it compares too my DLD

 

Kinda hard to get an exact OAL, but it is real, real close to 19-5/8" from the flange mounting to the end of the tailhousing. The seal sticks back anoutther 1" or so.

The actual tailhousing is 9-1/2" with another 1" for the seal.

Didn't think it would be good to measure to the center of the Ujoint cap due to it being a slip youke, and each could be slightly different.
