Lower Control Arm Question

[robfg67]

According to the MJ Parts Catalogue, there are two different types of bushings:

 

Part # 5200 1161 w/o ECE

Part # 5200 2539 w/ ECE

 

What is ECE and which bushing is correct for my stock ’89 MJ?

I know there's a type of factory hushing that has windows cut out of the rubber (for a less harsh ride, I guess).

 

Whichever ones those are, get the other kind. :smart:

[robfg67]

Does anyone know what ECE stands for?

[jpdocdave]

well i just did some searching, everytime it comes up it is saying w/ disconect axle. still it is very vague, but my guess would be w/ ece is w/ disconect axle. obviously no one has ever heard it called that before.

Thanks jpdocdave, that sounds believable!

Those were used in Grand Cherokee control arms, I think the WJ. I don't think they were ever used in XJs or MJs.

The bushings in our (96') ZJ have the windows,

same exact bushings (& arms for that matter) as XJ/MJ's, but with windows cut out of them.

 

I don't know when they started using them, 1996 was a (ZJ) change year, so it could've been then. :hmm:
