IRS upper shock mount - Permanent fix - Page 4

Sox · 26-03-2012, 08:53 PM

Ok, the people underlined already have, or have been allocated their mounts.
The rest still need to be made, however I do have 1 pair ready to go right now.

Ride is next on the list, so if you want to PM some details and $$, we'll get the ball rolling.

A couple more old mounts should be coming in soon, so I'll do another run ASAP.

1 - Brooksby88 - 1
2 - T3man - 1
3 - Ride - 1
4 - PROBLM - 1
5 - TS50 - 1
6 - DaveTE - 1
7 - Myts50 - 1
8 - tkfd - 1
9 - BOTTLEDUP - 1
10 - PEUTY - 1
11 - T3-TS50 - 1
12 - Stonepony - 1

Later - FTE217 - 1

Can you put me on the list for a set Sox and let me know when they are ready?
At this point in time they are certainly not a priority so am happy to be at the end.
Im in Western Sydney so can exchange our old ones with you.

BOTTLEDUP · 26-03-2012, 09:41 PM

Definitely still interested, I just havent obtained a used set to send you.

**Professor Farnsworth** · 26-03-2012, 10:01 PM

i threw my used set out when i changed them last year unfortunately

sk8xr8 · 15-04-2012, 07:20 PM

Thanks in advance Sox, cant wait for your delivery to arrive!

**Professor Farnsworth** · 27-04-2012, 04:01 PM

Sox i had my AU3 done with OEM mounts today and have kept the old mounts so just remember that down the track, as i'd like to get these ones re-made in the not too distant future as spares.

BOTTLEDUP · 28-07-2012, 09:49 PM

Heya Sox don't know if you're still prepared to build a set of these mounts, but I'm just about ready to grab some.

I think I might have a set here to do, if not, how soon can you get me your old ones?

BOTTLEDUP · 29-07-2012, 08:42 PM

I have to schedule it in with my friendly workshop, but I'd say approx 4 weeks I can have mine back to you. I'm currently trying to source a pair of old ones so as not to put anyone under pressure.

hales231271 · 18-08-2012, 09:42 AM

Hi
I have a set of used mounts.
Fitted new new ones 2 years ago.
Quite happy to send them over so you can build stock up.
Cheers

Hi all, just a quick update to this, I'm doing another small run of these over the next week or so, so will have a few on hand.

I've also made a small modification to the original design.

If you recall going through this thread, the rubber bushes did show premature wear because of the lateral forces on the small boss.

Using poly bushes appeared to have fixed this problem initially, but longer term testing has shown it hasn't.

I said I'll fix it if the problem shows itself again, and I have.
I simply weld a small tube with an ID the same OD as the Superpro bush, on the top and bottom of the main plate.
This then makes use of the entire bush to locate itself centrally on the plate.

Easy.

Only problem is, I have 1/2 dozen or so of you guys with the original design. Obviously as a recall, I will modify all of your units free of charge if you can get them to me at your leisure.
This won't cause a failure of any kind in the short term, but they will eventually begin to rattle.
Naturally if you continued to drive with it rattling, it has the potential to fail eventually (like anything which is grinding metal to metal).
I would like to see them all back here because of this.

Once this is done, I'm confident this will then last indefinitely, or at least until the poly bush itself wears out, but that will be a long time.

Lastly, I'm going to supply all future mounts, complete with the Superpro bushes, so they fit perfectly with the latest modification I'm doing now.
Obviously the price will go up in line with the cost of the bushes.

T3man · 15-10-2012, 09:34 PM

Thanks for the update Rick. Funnily enough my car is booked into the workshop tomorrow to have them fitted in preparation for Winton this Saturday. DUH, talk about timing! So I will camcel that and get them back to you on my next trip - the car can do a few more kms on the stockies I'm sure.

I was up your way yesterday can you believe?!!

BOTTLEDUP · 15-10-2012, 11:47 PM

Still keen for a set, haven't been able to find any spares around here but can supply my old units once swapped out?

Sorry for the hassle mate.

No problem, I'm doing 4 sets right now with 2 spoken for, so you can have the third set.

tangld1 · 24-10-2012, 06:12 PM

Hi Sox, I joined the forums only because this is the only place I have found with a solution tto this issue!!! Just convinced a mate to buy an XR8, and wouldn't you know, the rear to shocker mounts are stuffed. Just wondering if you have a set on hand, and the approximate cost, incl bushes. More than willing to send the old ones back after swapped over. thanks in advance, Dennis

Yep, I'll have a set spare.
I'm in the process of doing them as we speak, should be ready in the next couple of days.

tangld1 · 25-10-2012, 08:05 AM

Thanks mate. Would you be able to let me know how much? cheers

pstap · 28-10-2012, 10:36 AM

i made my irs mounts 8 or 9 years ago but just to let you know how the rear irs suspension works The shocks are mounted on a angle so when the car goes up and down the shocks has to move on 2 axis at the same time thats why ford used a rubber mount .

Can I pay you the money now?

I'm still keen, btw.

Will send the old set back to you.

So how is that different to non-IRS? I don't believe that is the reason why Ford used a large insulator; it is to do with NVH levels and that's about all. The fact is that by using the type of mount they have they in fact restricted the movement to which you refer and this is probably the main reason for the insulators to fail so regularly. This "new" mount allows the same movement but does not impede it, therefore (like on a traditional live axle) the upper mounting should have a much longer service life.

PS. Rick, I'll be in Windsor next Saturday morning so will drop by your place. I'll phone first to make sure you're about.

pstap · 28-10-2012, 09:27 PM

there is heaps of different between irs and non irs on how the rear end works and responds but i not going into that but i know ford stuff up on the au irs and thats why the ba does not run a rubber bush, nolathane tried to fix the problem but failed also i know the person who was working on the project and he also told me the problems with the au irs and ford had to redesign the irs for the ba, look i was only helping you guys on why the bushes fail and how to fix it .i done this set up 8 years ago and now i run a full adustable coilovers shocks on a irs diff

Well, only in that each side can move totally independent from the other.

As T3 said, the way in which the shock moves within it's entire stroke is little different.
The solid axle shock moves on 2 axis as well, just to a lesser extent on the second axis.

In any case, this is not relevant to the way the original mounts have been designed, as conventional mounts can tolerate movement on another axis.

The B series is entirely different.

Actually you haven't mentioned your method as to how to fix it.

That's not a fix of the original mounts, that's a totally new shock spring assembly. Quite expensive, and not totally needed for road use.

My fix uses all existing parts (exept for the mount itself), and a small serviceable inexpensive bush which will last a long time.

Rather than tell us what you think we're doing wrong, and what you've done right, why don't you spill the beans and tell us exactly what you've done?

tangld1 · 30-10-2012, 06:27 PM

Thanks for the updates sox, can you put me list for a couple asap? PM me with details so we can get the ball rolling, Cheers.

Will do.
I'm hoping to have them finished tomorrow, so will be in touch with all the people who have made contact over the last few weeks.

pstap · 30-10-2012, 07:56 PM

Thats what I said before that the ba is different to a au IRS The au shock is mounted on a angle on a IRS diff .look at my pictures I put up of what I done to my mounts under pstap update 347

Ok, your first effort is similar to what I've done.
What went wrong with them?

The only problem I've had is with the boss on the bushes not locating securely enough, these latest ones have rectified that issue.

The coilover setup looks great, but as you know, it's not for everyone.

**Peuty** · 30-10-2012, 08:54 PM

I will transfer money to you tonight to secure myself a set ASAP.

PM me your details....

Cheers

pstap · 30-10-2012, 09:03 PM
