OK, not sure if I even termed this right, any way I recently got my dual cases installed and had the rear shaft shortened. I am wondering if the rear shaft was shortened too much. Shaft was not done 'professionally' but the guy had the jigs etc. Driving the truck ('81 Toyota Trekker) at speed I don't get any abnormal vibrations etc.
But what concerns me is if there is enough contact on the rear slip joint?
Rear springs are fairly flexible (5" Trail-Gear)

 

Looks normal to me. You're not seeing splines yet, so there's quite a ways to go.

In the end, the acid test is to put the axle at full droop and make sure the DS is still engaged on the splines.

 

slip yoke is the proper term it's a spline gear.

you look ok, you want it to be about in the middle of it's travel distance

 

cool, I took off the slip yoke (thanks algranger) and measured, I have got 1 5/8" of spline contact

 

hmm it does look a little short huh?

are you gonna be wheeling it much? theres the possibility of stripping the splines off although i ran one about like that for over a year when i was 16 (meaning i drove the hell out of it) and never had a problem

 

yeah, I am running stock 2.28 in the front case and 4.7's in the rear case..plan is to wheel it..

jacked it up with the high lift to check full droop per TC's suggestion and it extended further. so it looks like the guy is making me another shaft...

 

it is short, but should work.

 

Short X2. Might leave you unhappy on a trail.

 

Seems if memory serve me. The rear slip is a total of 5" you want 1" for up travel and 4" for droop. Hope it helps.

 

Could always add a spacer if a new shaft is going to run you too much:

Generally want about 1" - 1.5" of compression travel from rest for a rear shaft, depending on how far you can compress the rear suspension.

 

Cool, I might be ordering one from you.

other question I have: should the slip yoke be mounted at the Transfer Case instead of the Differential??

 

Slip yoke end doesn't matter, I put it down for the little extra clearance because the diameter is smaller
