Low speed Vibs after lift.

Hello folks. Before posting this, I have tried to do some research. So I did my lift last weekend. Lift is 6112/5160 with OME medium duty leafs, and JBA upper control arms. Roughly 2in lift. I also did the ECGS bushing. The bushing install was a pain. I hammered on it quite a bit, not realizing it didn't have to be flush. The truck has been to the alignment shop and came out great with that. I'll post the printout. Everything is torqued down to spec also.

So the Vibration. The vibration happens only when slowing down at 20mph to stop. I feel no vibration during accelerating or traveling at higher speeds nor do I hear anything. I can feel the Vibration in the stick shift handle and maybe a little in the steering wheel and you can hear it, just from the vibration.
I purchased the OME driveline spacers and am waiting for those to arrive. Anyone have this problem after a lift? Did I maybe up the ECGS bushing?

 

Probably some sort of axle wrap occurring, as you decelerate your axle rotates and slightly binds the drive shaft with the change in angle. Does it feel like a shudder? It's best practice to measure driveline angles before and after lifting to see how its changed.

 

Maybe like a shudder. Thinking about attaching my gopro down there and watch it. You think those OME drive shaft spacers will help? Maybe the Plate the UBolts go through for the rear axle isnt lined up properly? I cant see hownI could screw it up, idk.

 

2 inch lift, get 2 degree axle shims and install them under the leaf pack.

 

Idk if I've seen the shims. I'll have to do some research.

Like this? Angle it a little?

 

Yes but keep in mind you'll also need extended head bolts to replace the ones that go through the leaf pack. @HeadStrong Off-Road has them

 

Yeah dude! It corrects the angle of your driveline. Should fix all the vibes since you’ve already taken care of the ECGS bushing!

 

I had an OME kit (Nitrochargers, 887 springs, medium Dakar leafs, kept the oem uca’s) installed by a reputable off road center and had a slight ‘washboard’ type vibration, primarily on deceleration between 24-18 mph. The shop said that the vast majority of the time they can mitigate any vibrations and that with all the Tacoma’s they have done there was only one other that they couldn’t ‘fix’. Even after an entire day of the shop trying multiple driveline configurations, drops, shims, etc. the vibration was still there. After multiple rounds of troubleshooting, and a call to Arb USA, the fix seems to be adding a modest amount of weight to the rear end. Their theory was that lightness of the Tacoma rear not compressing some portion of the medium duty Dakars (or something to that effect) and changing the driveline angle in deceleration was just enough to create the vibration. Added some weight and so far it made the vibration barely noticeable. I’ll be testing this weekend to see just how much weight is required and if it makes a difference where it’s placed in the bed. There are a lot of other solutions that may work for you, thought I’d let you know what worked for my truck.

 

Hmmmmmmm. Well I did get the medium duty for my SOS Concepts Bed rack and Tepui tent that I will be adding next week. Maybe the extra weight will help. Thanks for the info!

 

Aded weight to the rear, via filling up my fuel tank. I don't really have the vibs anymore or experience any Axle wrapping. I took a video. Please excuse the banging sound, Just fuel moving in the Tank. Also almost got stuck. Thought a trail was wider of the road but it was a atv trail, and the part coming off the road was steep AF.
