measuring for front drive shaft
« on: Oct 05, 2019, 01:29:40 PM »
so I just finished moving rear leaf springs up front on my 85 4runner. now it's new drive shaft time. my problem is I need 3 measurements for building new drive shaft. ride height, full bump, full droop. any tips or tricks for compressing front end under vehicles own weight. I don't have access to a lift. just a floor jack. any insight is greatly appreciated. thanks

Anybody with a clue should be able to build your shaft with a single measurement. (flange to flange at static ride height)
If someone needs more, seek a second opinion.
Dont waste your time without going long travel either

Actually  I dont blame shops for asking that. If that shop is not a toyota specialty shop they have probably ran Into it a few times where having to deal with the customer being unhappy since their shaft keeps coming apart under droop.  And of course it is all their fault since they welded it together..If they have all the measurements they can let their customer know they need a longer travel spine.

With rears up front you almost always need longer travel spline.

IMHO, you always need a long spline up front, I got mine from Dave'z Offroad and it has a heavy duty, 14" long spline, still uses Toyota U-Joints!! The d-shaft shop only wanted static but top and bottom of the flange!!

Marlin Crawler can build you a driveshaft with a long slip.  Just need the static measurement at ride height from flange to flange.
