OME 90000s on DC 4x4

Im going back and forth with ARB about the clunking over speed bumps, roots etc with my 884/90021 front lift on a 2006 DCSB V6 4x4. They insist it shouldn't make the noise, I tell them it's a prevalent problem.

Their suggestion is 90000 shocks. Does anybody run these on a double can 4x4 v6 with no extra weight? I'm not even sure the rebound dampening is going to be much different and I'm worried the ride will just end up being rock hard in addition to the speed bump clunk.

A lot of unanswered question in those search results.

more curious if someone has gone from 90021s to 90000s and experienced a solution to the clunk/topping out of the current setup.

 

Okay.
Hmmm....thought there was some stuff on the clunk issue in the OME questions thread. Could be wrong, probably wrong, mostly likely.....am wrong.
If anyone knows, that would be @OZ-T

 

I'm going from the 21s to 00. Hope to get them installed this weekend.

 

Yeah, I read through pages of threads on the clunk issue and @OZ-T seems to be the authority, but he appears explain it as an unwanted "feature" of the shock.


Re the 90000 vs 90021, I'm concerned the 90000 would make things worse. Would the shock made for heavier loads have even less rebound dampening, and therefore more likely to top out on a lighter truck? Still this is ARBs recommendation.

 

Please report back. What was you're reason to switch?

 

New shock assembly. Saw that 00 were recommended for the 886s. Figured why the hell not.

 

Dumping the OME shocks for 5100's cured the Over Speed Bump Goes Clank for TW Member @Crom

 

That's an option. But this thread stating the same issue with the 5100s has me concerned

https://www.tacomaworld.com/threads/ome-885-5100s-lr-uca-topping-out.266820/

What is driving me nuts is this appears to be a gamble, some get the clunk some don't.

 

That guy's hub to fender measurement was 24" and his noise went away if you read to the end of the thread

I still think he installed something incorrectly and thats probably the only thread I can remember on a top out noise with 5100's but there are tons of them with OME shocks

 

I've talked to both owners (me being one of them) of said shocks and both OME "top out" with a thud sound like this video.

The go over speed bump goes clank sound is different from topping out. In my experience, going over speed bump clank is most likely a coil contacting a stock UCA under compression.

COuld be a million onther things too, just wanted to share what I know. Good luck.

 

Thanks, that is pretty much what I am hearing. There's no contact with the coil, or no scratches or rubbing. All connections are tight. No play in the control arms, though not sure if I could tell if the bushings are shot by shaking the arms. And this didn't start until the OME's were installed.

I got a 2" lift from the 884s. ARB said that's too high. But it jives with what Toytec and owner experiences here have reportered. I have just under 2" of droop on each side.

Just concerned their solution is going to cause more trouble. A move heavy duty shock should rebound faster and would only make the rebound clunk worse, no?

 

One odd thing is the top nut spins on one side. But the nut is tight enough to compress the bushing. See photos. Does this indicate anything?

 

Update:

ARB did in fact send a new set of OME 90000 shocks gratis and they were installed today. Problem solved. No more "goes clunk over speed bumps".

Can't say for sure if the 90021 shocks initially installed were defective or the valving on the 90000 shocks are just better suited for the spring rate. Curious to know if this problem occurs with both models.

And the ride is better IMO. More solid, less brake dip, better cornering, etc.

Edit: I'll add that Toytec was pretty much no help in this matter, blamed the installer (who is approved and recommended by them) and refused to warrant/replace the shocks. I won't be doing business with them ever again.

 

I seem to be having the same problem. I installed full ome kit yesterday with 885 springs. Who did you get in contact with at ARB to get this taken care of? Why do they sell shocks with springs that do not work together...

 

Somebody figure out if the 90000 has a longer working length and see if that's why it fixes it

 

Mine were the same length extended and compressed.

 

yep, here you go.

 

Hmm so it would make sense that the billies would fix it but maybe the reason 90000s would work is the valving causes the spring not to extend as fast after speed bump so it doesn't have the momentum to over extend all the way...with the same springs, a stiffer strut would result in less overall travel in an impulse situation like this...thoughts?
