Hi all, I recently purchased an e-locker for my front M186/D30 in my Willys for my regar. I decided to take it to a shop to have them do the install, alongside the regear, because I felt I was getting in over my head.

I purchased the locker (eaton p/n 19818-020) and the eaton install kit p/n K-D30-186 as per their application flyer. The shop just called and told me that the bearings in the eaton install kit are too small for the e-locker. They say they're the same size as the spicer bearings in the 'standard' master install kit.

They're reaching out to Eaton tomorrow, but I wanted to see if any of you guys knew if there's another install kit for the M186 e-locker that I didn't find? Or did I just royally screw up in parts?

They likely just messed up the parts. It uses the same bearings from the Master Kit, as they mentioned.

edit - this was in no way the shop’s fault, totally mine for not reading the manual. Original text below for transparency.

***Well crud. That causes me to lose some confidence in them.***

Update, I just called and talked with Eaton - the e-locker runs a thicker shaft, needs bearings with a larger ID (same OD). For future people, they said the bearings in the rebuild kit are for all the carriers except for the e-locker.

According to the techs at Eaton, the bearings needed are off the shelf bearings, p/n Lm102911 and Lm102949, 2x needed of each.

Yeah, unfortunately you don't know unless you read the instructions. There should be a big * saying that it requires special bearings. Found out the hard way myself.

I knew I should have opened the box and read those :LOL:

But in seriousness, their application flyer has an asterix for nearly every other carrier on the list with individual, specific instructions on what extras you need. My fault for assuming I was in the clear after seeing that they didn't say anything special about the m186 e-locker. Ah well.

I had an Eaton EAT19818 installed on my 2019 JLU sport when I wend to Dana 4.88 gears no problem. Got it from West Coast Differentials before Eaton had a e-locker available for the M186 axle.
