Default Samurai SPOA Lift Questions

I have several questions on the SPOA lift that I'm currently doing to my Samurai, which I bought from Rocky Road:
  1. The garage that is doing the lift made a terrible mistake and cut off my lower OE spring perches; he didn't realize that the new perches will be resting against it. What do you suggest?
  2. There is quite a big gap between the new perches and the axle housing (the type that wraps around the axle housing and rests on the orginal perches) is that normal?
  3. The lower rear shockmounts are an angle piece of steel and the shock stud. Where exactly is this angle supposed to weld?

Any quick help is highly appreciated.

How hard is it to find another axle housing where you are? It would be easier than trying to fix what they cut off. The whole reason for the design of the perches you bought are to relieve the stress that welding the perches directly to the axle housing can cause. Otherwise I would add a half sleeve of thicker tube to the exhisting axle housing were the new perches would go and then weld the perches to it. The axle housing is very thin, it needs something to strengthen it. They cut off the part that makes the perch do that.

You should have a pair for the rear axle that look exactly alike. Then there sould be a large and a small perch for the front. Small perch fits over the drivers side and large fits over the strengthening plate on the passenger side. Since the guy already cut off the original pads, there should be no gap. With the perches still in place - sometimes they make the arms a little too long and old you have to trim them a little to get the perches to fit flat down on the axle housing.

The mount attaches to the axle at the rear and bottom of the tube. This is about an inch or so to the inside of the perch (towards the diff).

(pic now working...)

Here is an old article from iZook that can give you a more in-depth feel for the installation:

Wow that sucks! I have a Breeze industries kit that doesn't rely on the lower perches that seems to work good. I don't know if it is cheaper to get their kit now instead of monkeying around? They are in Canada so your dollar is stronger and you would get it for a good deal.

Thanks guys for the help. I'm really angry at that shop; they just went and cut off the U-bolt pads and the lower OE perches. Fortunately I caught him before he does the same for the rear axle, so the rear is fine. The front one only is hurt. Here's a picture of the damaged housing.

Fortunately, I found two full Samurai Chassis' lying on the floor of the workshop, which include axles, diffs, transfer case, springs, and shocks. I'll ask him to give me the front axle housing of one of them. I hope he agrees, he has to pay for his mistake.

Ah, now I see the picture (wasn't showing when I first opened the thread). Ok, now it's clear, thank you Bill.

It will work if you don't push your vehicle to its limits. But if you do, my opinion is that it will damage the housing. It is the cheaper solution. And I've already bought this kit, no point of changing it now.

I have used many of the RRO perch sets because I like how they work. But to be completely honest, the first time I installed one I did almost the same thing. This is a case of not knowing the equipment before you install it. In my case I didn't cut off the perches, I cut off the stock strengthening plate that is on the top of the axle housing. This caused larger gaps when I tried to fit the new perches in position. The RRO perches are made to fit over the extra metal.

I still have my lower perches and trust me I do push mine to it's limits......and beyond!

He should give you a new housing since he screwed up. Good luck and happy wheeling.

So what did you do? Did you put them back on? Or fabricated a different one?

Ok, good news, the workshop manager gave me his axle that was lying on the floor of his workshop. So the mistake has been undone. I wasn't sure whether the ring and pinion ratios are the same, so I swapped out the whole differential.
