3rd Gen OME Dakar Leaf Springs Making Contact With Shackle

Taco World,

I have a '16 DCSB with OME Dakars (light duty). After installing new suspension (5100's, 888;s, LR UCAs, and the Dakars) I noticed a clunk/rub sound coming from the rear end at low speeds, particularly when hitting driveway curbs, harsher speed bumps, etc and at an angle. I crawled underneath and noticed the second leaf in the pack was making contact with the shackles.

In an effort to avoid having to grind the end of the leaf to create sufficient clearance, I installed Archive Garage Hammer Hangers. These move the mounting point slightly toward the rear and lower-- which did help, and these are awesome for reducing chatter, but the noise and contact still persists on sudden rear suspension hits at low speeds.

My local mechanic who does a lot of suspension work on Toyotas says he's seen this before with Dakars, but I haven't found any relevant threads on TW. Has anyone had this issue before, and if so any fixes yet?

Clearance Issue and Rubbing (see rust spots on shackle):

Old Stock Hangers:

New Hammer Hangers (again, these are awesome for improving ride quality)

Another shot of the rubbing/rust spots:

Just for fun:

 

I haven't seen anything about that on here either, sucks though. Hope you get it figured out soon

 

Bump...

 

Big adjustable wrench, fold the contact spots out about half an inch. Done

 

Contact hammer and see what they think.

 

Is your bottom bolt up installed backwards? Shouldn't the nut face out ?

 

Thanks for the responses.

Looks like you’re right— it’s reversed from stock after the Hammer Hanger install. It was done this way on the install video I referred to as well— see any potential issues with this?

Thanks for the advice. I’m thinking I’ll bend the shackle in combination with rounding out a few inches of the square edge of the second leaf to get a little more clearance in there.
TBH I don’t really want to do either on a relatively new truck, and I’m not thrilled that nobody else has had a similar issue— but hey, it’s a small problem.

I’ll post pics with the results. Thanks again for chiming in

 

My recent rant on Dakars, I can't stand the way the secondary leaves stick into the shackle, it is excessive. Dont be afraid to modify to your needs, modification is often needed for aftermarket parts, I try to keep my parts out of that zone

Please call up ARB/OME and tell them about the issues so they can resolve and update their design, you'll feel better

 

I was wondering what the hell that noise was. Got a link to the new hangers? How much did this improve the ride? Straight bolt on or???

 

They require drilling the factory rivets out, then they bolt on in original holes

Hey, another eastern offroader, I didn't think any others existed!! What town is your Toyota-experienced mechanic located? VA isn't that far away from southcentral Pennsylvania!!

 

Really, cause there is a shit load of off-roaders from PA.

 

Must be upstate. No one around Harrisburg seems to know anything about offroad equipment/suspension.

Hey bud, not from Pa, but I stalk a forum often
Pennsylvania

Also, Rausch Creek, AOAA and FRO are like a stone throw away from you, I wish I'd live so close to those...

Some of those threads get busy around some events



@GC4x4, sorry for off-topic stuff

 

Don't bend the shackles, you will lose structural integrity. Instead, trim away where the leaf springs are contacting.

 

I just got an 2 inch OME lift with HD leaf packs and the installers ran into this problem. They cut the bolt to eliminate the extra threads and provide a small bit of clearance. I haven't had issues since, but haven't wheeled it hard in off-camber situations yet. (maybe I never will?)

Interested to see how it all works out.

 

Do you have any pics of what your installer did? I just looked at my truck and have the same issue.

 

I will try and take some pics tomorrow.

 

Were you able to get those pics?
