Bushing install?

I have changed a few of these and there should not be need for any machining. And deburring is just to take down rough edges as Lambert says.

I used a press for the bushings and had no problem installing. Have put in original type and two kinds of offset ones. Hardly needed any deburring either..

I've used my 50 ton press mainly for building rifles. Pressing steel barrels I to steal trunnions or receivers.

The size difference between the control arm ID and the bushing OD was 1.6mm. The bushing have a machined slope to one edge to facilitate pressing. But it seemed a sufficient size difference to justify some reduction in the 1.6mm size difference. Thoughts?

The bushing if course has a steel ring and center separated by rubber. I've never pressed bushings so I don't know what kind of compression tolerances can be expected. But coming from steel to steel pressing it seemed likely reducing one or the others surface might help. I'm not even sure the slopped edge on the bushings fit into the control arms ID. And they seemed adamant it wouldn't press and something would break.

I am concerned that the outer ring in the bushings are now .8mm thinner. But regardless who was wrong or right. I felt it easier to replace bushings later than control arms. If something failed.

Thoughts? Is 1.6mm a normal tolerance offset for a bushing you would normally press? Have the bushings been compromised by their .8mm reduction?

I did some querying on Grok. Apparently the tolerances or interferences I am used to in rifle building are similar to car parts. 1 to 2 tenths of a mm seems normal. And although .8mm is pushing it. It's ok. Could result in a 20% loss of life in the bushings. But will most likely be fine. I'll keep an eye (and ear) on it. And probably eventually just have them replaced with better bushings that fit properly.

I'd follow up with ARB but their support for the Phillipines is fairly non existent. And it's a waste of time with the Phillipines distributor. It's a woman agent with little tech knowledge -who refuses to put me in touch with any tech type person. Not that one probably exists anyway. Lol. 

Ah. Life's an adventure in the third world. Lol! It's why I'm here. 

Anyone know of a specific better bushing that is in a sweet spot between quality and price?

Forgive me for asking but I'm curious, the standard suspension bushes are bonded rubber with an inner and outer metal sleeve. When the old bushes were pressed out, the outer metal sleeve was also removed? It's entirely possible to use a press tool that doesn't quite connect with the outer part and just shears the rubber parts out leaving what looks like a fairly clean bore but is actually not the bore in the radius arm. It's just i keep coming back to the idea that a reputable company like ome arb would not have gone to some effort to correctly size their parts?

 

 

They are intact. This is one of the originals. 

I agree with you about OME/ARB. But it could be due to the fact I'm in the Phillipines. I contacted ARB. As there is no ARB Phillipines. And tried to find any information I could on the OME 40mm lift for my Suzuki Jimny. As Suzuki is not an option on the main ARB sites lift kit look up. They don't even list the kit for the Jimny. I contacted them looking for install instructions. And they had nothing. And kind of blew me off. As I was contacting them from a third world market. They do have multiple distributors here. But they have little to no information either. 

OME itself does not really have a web presence. It appears to me that ARB must have bought them. ARB did produce a YouTube video about the lift. But there is little to know information in their site or customer service about the Jimny OME lift. 

The Phillipines is a weird market. For instance Suzuki sells Jimnys to PH auto groups directly. These auto groups buy the rights to the brand and to sell what they buy from Suzuki in the PH. Often times minus basic equipment like head units (mine was a pos PH android head unit you've never heard of), and once PH takes possession Suzuki Japan has little to nothing to do with it. Because PH is a corrupt business market a few families control everything. And own monopolys with no competition. 

So often times the PH gets sent the leftover batches or the returns or the lesser quality. Because the distributors dont have to care about their customers - because they are the only ones you can buy from. I wouldn't be surprised if the PH distributors bought seconds or something or didn't care if QC was perfect for a cheaper price. Who knows? This wouldn't be the first time I was screwed over by a PH business. Lol. 

But I've always had a high view of ARB and OME. Especially OME. But their site does not look like a company still in existance. Continuing to market their products. It looks like they got bought by ARB and ARB can't really afford to supply support to these small third world markets. It's not like AU or UK or the US here. It's a mess. Lol. Nothing makes sense. And just hoping to get a better quality product from anywhere. And a certain percentage of everything you buy here is suspect. It's so common you just expect it. 

I was disappointed when I contacted ARB and was basically told sorry we can't help you. Lol. 

But again. Not surprised. It's the Phillipines. The third world does not operate like the rest of the world. Free market capitalism and democracy does not exist here. 

But I did ask AI about these bushings. And it did find forum and group posts about others routinely having to fit bushings like this. I did not ask for specifics. And AI links get blocked even when they give them to you.

I also sent an email to the ARB distributer here in the Phillipines that sold me the lift. Waiting for their response.

ARB have an online support channel that I have found quite responsive on the few occasions I've needed to use it - that link will take you to the US website, and whilst the Jimny is not sold in the US, the US team supplies & supports the Jimny accessories to the Mexico & Caribbean markets - I'm in the Caribbean and I've sourced product both from ARB directly and also one of their larger resellers in Florida.

I've been paying close attention to this discussion as I'll be doing the same suspension upgrade early next year, and the installation of the caster correction is the only step in the process that I am not equipped to handle.

I find Lambert's suggestion of the OE bushing possibly coming apart to be quite interesting, perhaps because, like him, the idea of ARB/OME supplying a product that requires any significant machine shop work doesn't sit well - cutting plastic trim and drilling holes to install a bumper or a snorkel is one thing, but precision reaming a radius arm is something else altogether.

There is however a flaw in Lambert's idea, if the rubber in a bonded bush like the OE is pushed out of the outer sleeve, it will usually leave "chunks" of torn rubber in the sleeve, and this should be quite obvious.

Reaming the arm does not sit well with me as it would prevent the use of OE or OE sized bushes at some later state.
