Hey guys.
I'm getting set to finalize the engine mounts in my project. I've got a lot of uncertainty around the Drive line angles and transfer case output angles that's making me gunshy about locking in the vertical position of the engine mounts.
I think I've roughly simulated the unlaiden ride height with the engine weight on the chassis and a couple of stout friends of mine sitting on the front of the chassis.
(That wouldn't include any cargo or passengers)
My rear pinion angle is 4.3 degrees and my front is 12.8 degrees. I'm trying to decide whether to try to angle the output angle by adjusting the engine height or not.
It seems to me that anything I do to try to match the rear angle will put the front angle even further out of whack.
I understand the basic premise that the output angles and pinion angles ought to match. I'm also aware that the stock front shaft is phased to account for the variant angle between front pinion and front output but I'm not clear on how much angle that phasing accounts for.
I've been trying to find info on the stock configuration but coming up dry.
Can anyone tell me what the stock configuration looks like. Is the engine typically level? or tilted rearward or forwards? How much difference is normal between the front and rear pinion angles?
The chassis is originally from a LWB RRC but is sitting under a 109 2a. I'm not sure if it has stock defender springs or lifted. (My best guess at unlaiden ride height gave me about 21" from center of wheel to top of wheel arch). Transfer case mounting is rearward from "stock" by about 5".
Thanks for any info you can offer!
