Jeep Willys Tesla Build

I am converting my grandfather's M38A1 Jeep Willys to electric (as well as restoring the jeep).

Some features include:
Tesla Model 3 drive unit;
narrowed Dana 44 axles from a 1975 Jeep Wagoneer;
Jeep YJ leaf spring conversion;
Orion 2 BMS 132s; and,
a Chevy Volt battery pack.

I am just finishing mounting the Model 3 drive unit sideways in the middle of the jeep. The front and rear drive shafts will each connect directly to the stock drive unit differential outputs. I plan to mount the entire battery pack (stock fiberglass shell and all) in the cab with the top of the "T" sitting where the rear bench seat normally would go. The car should be VERY torquey!

Awesome build and trying to do something similar. X2 on the controller question.

Looking good! Any driveline vibrations from your early testing? I am doing something similar on my project and trying to figure out if I should just machine the half shaft stub from the motor to accept a spicer flange yoke or might have to do a weld on yoke for fitment but wouldn't be ideal. Also if you want to sell the open dif PM me. Might be interested in trying to weld it for a locked dif. Cant afford the limited slip right now.

Thanks! Initial testing was very good! Here’s a separate thread focused on the driveshaft adapter if you’re interested:

On the LSD install topic:
I would recommend not wasting your time trying to salvage the bearings from the stock differential. I used one Shaeffler 6309 and one Shaeffler 6211 bearing. The stock carrier had SKF bearings on it but Shaefflers were what was available. I couldn’t find meaningful markings regarding specs on the stock bearings. The 6211 and 6309 are the correct size and have similar performance specs to what people are using for the LDU LSD install—I couldn’t find any information regarding the model 3 LSD install.
I recommend watching these two videos before installing the LSD in the model 3 motor:

I may have missed it, but what's the firewall snout for?

The front of the Volt battery sits in there. The Volt bulkhead with all the battery coolant connections and HV connections are right inside there. It has a pass through on the bottom for the hv and coolant lines.
