Awesome. Thanks!

Yeah, I suspected that the previous owner had put an add-a-leaf on, but hard to tell what it is. The spring perch is there and has the stock u-bolt plates (with the shock mounts), but my mystery piece was bolted on the underside of those u-bolt plates. I think I might have figured it out though. That extra backing plate piece has smaller diameter holes, so I think they threw it in there to keep the smaller u-bolt and nuts from pulling though the stock 14mm bolt holes. Based on that cobbling together of parts, it wouldn't be a surprise if these leafs are off some random vehicle with similar size springs.

My 89 has power windows added (by the previous owner) and window power supply is tied into the thick brown wire, which I understand to be the ignition power supply. Everything works, so I believe that is the correct one. I've yet to figure out what to the the power lock switch supply to though.....

I had some knocking coming from the rear end of my 89 Comanche, so I started doing some investigating and found that my axle was rocking back and forth on the spring when torque is applied to the wheels. It seems like the inside u-bolts nuts were not tightened down properly and based on the wear on the bolts, there for sure has been movement. Once I got them unbolted, I found that the backing plate that was between the u-bolt nuts and the u-bolt bracket on the underside of the axle was also quite bent (picture attached). I can't find any sort of parts diagram for the Comanche spring-under axle. Does anyone know what this backing plate part would be called or where to get another one? Is it even a stock part? I also found that the u-bolts that were on it seem to be a lot smaller diameter than stock Comanche bolts and now I'm not even sure that the leaf springs are actual jeep springs. Can anyone identify them from the picture below? They are some 4+1 configuration, so they could be the 1440lb springs, except that the truck has a 4.5" lift in the front and it sits level, so there must be some sort of lift in the rear beyond just the extended shackles. The spring bushings are quite worn, so have been debating whether to replace the bushings or just get new springs, but I kind of want to figure out what I have before I can do either. Plan to get new u-bolts too. It is an 89 Comanche pioneer 4wd short bed with a Dana 44 rear.

1989 Jeep Comanche Pioneer 4.0L 5 speed manual short wheelbase Winnipeg, Manitoba I recently purchased it. Still on the road and in decent shape but needs some restoration. Has the sport bar and lights in very good condition.
