making my own tcase drop

[james750]

Since I can't afford a SYE and DC driveshaft and I am going to an 5" lift with SOA rear, I need to put in a tcase drop. Based on some of the kits I have seen for sale, I think I can make my own for a whole lot less than the price of a kit. If I were to get 4 1.5" spacers and some new 1.5" longer Xmember bolts would that work? OR will it not have the strength I need for the Xmember?

T-case drop in our trucks is a bad idea.

 

You may slightly benefit your rear DS, but at the cost of your front. Angling the back of your T-case down just angles the front up.

get a longer shaft and have it shortened. keep your belly up high. tc drop = :dunce:

 

 

 

(i had to use the dunce smilie since we don't have the ghey one.)

everything you said is true...

 

if you have a cherokee.

 

comanches have NO reason to have SYE. because the wheel base is longer, the driveshaft angles don't get too extreme even at 6.5"...you just need to have the right drive shaft made.

 

you'll also benefit from using a YJ slip-yoke as it allows another 13 degrees of downwards flex on the drive shaft...reducing chances of blowing a driveshaft ujoint at full droop.

 

 

I have an SYE in my 87 shortbed...for the simple fact that the entire transfercase was only $250, and I can now drive home even if I destroy my rear drive shaft. had that case not been available, I wouldn't have gone out and bought an SYE to install.

There are good reasons for a SYE on a Comanche, even a stock one. But it is not needed for a 5.5" lift.

:agree:

ok, I will just look into getting my driveshaft extended then (if needed). I was afraid I would be fighting some bad u joint angles.

 

With 5.5" will the slip yoke be extended far enough to warrant a longer driveshaft? I think it probably will.

yes you will need a new drive shaft, unless you've got a dana 35 now and are putting a dana 44 in it...then the driveshaft might be long enough.

 

get a YJ slip yoke, it will take away the vibes.

Lengthening a driveshaft (by adding a short length of tube to the existing tube) is not recommended. Find a longer one and get it shortened. :thumbsup: I would hang on to your current one for the day you upgrade to a Dana 44. :D

I'm going to an 8.25. Will I need a new DS with that?

[Pete M]

Not sure. Someone else here should know that though. :thumbsup:

[JeepcoMJ]

not really any way to know if you will need a new DS or not until you get into it.

 

will you be able to run your existing DS? probably I was able to drive my 89 with 6.5" lift and stock DS with a dana 44...but if the rear drooped it fell out... you'll most likely have to get it retubed though, or find a longer one to get shortened
