OME Coil Spring Problem in Fortuner

[Monty]

Last September I put OME suspention into my fortuner. However I was down in Ponta Do Oura this weekend negotiating some challenging terrain and experienced an unusal sound from my rear suspention...the sound of a spring recoiling.
When I got back I asked Toyota to put it up on the lift to see if anything was visibly wrong and found bothe rear springs at the top had worked their way out of their rubber housing. As the spring came under compression in its offset position,it would recoil back into the housing where it was sposed to be seated thereby giving that unusal recoiling sound I heard from the inside while driving. However as I drove on and worked the suspension,it would work itself out again.
Has anyone had a similar experience?

OME guys said it could be one of two things or bothe....either the mechanic who fitted the coils never seated them correctly in their rubber housing in the first place or else the springs were put upside down. The latter never applied in this instance. I would have at a guess that it was just poor attention to detail by Toyota and hope now that they have been properly set,the problem won't reoccur.

Never had such an issue with my OME.

Also haven't experienced that before.

Is this only when your wheels articulate on serious off-road conditions with the wheel hanging in the air?

[Monty]

From what I've seen and heard I would summize to say that the springs weren't located properly and when I put the vehicle into some terrain which articulated the suspention severely the problem was quite audible which wouldn't have been heard had I been on open road when the suspention is doing the least work. But yes,getting back to your question,when the suspention was just hanging,thats when the spring would work itself out and then when it was put under compression it wouldn't seat back correctly and a few seconds later you could hear the spring recoiling back into its housing but then it would come out again the next time the wheel hang freely.

OEM - Original Equipment Manufacturer
OME - Old Man Emu (COOL AUSIE SUSPENSION)

Your post says OME , did Toyota fit your OME coils

If it's OEM -- Toyota must solve FULL STOP


Coils have normally a FLAT top and Round bottom -- that's the right way up.

COILS are not fullly locked and are just seated, and WILL in EXTREME articulation slightly move down and reseat afterwards - this is the reason for the rubber/steal "cones" at the TOP.

Thanks Jas

I am well aware of the workings of a spring and the componentary involved...toyota have accepted that it was a fault of theirs and I hope thats the end of the problem.

Thought it would be interesting to hear if anyone else had experienced this. Thanks for your input!

I have family over and his fortuner sounded like it was bottoming over bumps

I had a look and found this

Could the coil be upset down and walking out of the cup? Is the coil one side flat and one aide angled?

I dont have the facilities to take the coil out to look and maybe rotate

I did manage to get the coil seated again. Havent driven yet to see if it solves the bottoming feeling yet

Bump

Bump

What limits the swing arm's vertical travel?
Shock's max extension?

Does not look right.

I think the shock is the limit.

I had the suspension at max droop and couldnt get the coil out. I just jimmy'd it back with a tyre lever.

Maybe wrong shocks fitted?

[TRON]

Are they OME or OEM?

When had OME installed they replaced the coils as well. On inspection it was not that the vehicle was not level. The coils climbed out of the top holders after going over the first bump. Found out that they never replaced the coils with the correct size - height. Coils were too short.

[MariusFourie]

Coils were replaced

Cant see markings. Not sure what was fitted. I suspect original toyota

Shocks as follows

[4ePajero]

M8067 seems to be the correct shocks.
Possibly incorrect coils then.

Maruis did you come right with the shocks and coils. I also wanted to fit new monrow gas magnums. concerned now, was it the incorrect coils? who assisted you
