Vibbbrrraaatttions!!

2017 TRD Off-road 4x4 DCSB
1" wheel spacers
265/75/16 on stock wheels.
Installed Bilstein 5100 on all 4 corners.
OME 887 on the fronts .
Single add a leaf on the backs.
2" lift front and back.
Whole setup from Headstrong Off-road.
Got it installed no problem but now have a slight vibration when accelerating at 18-25mp. It's worse at that speed when stopping.
I've tried the carrier bearing drop. Made it a little better, but still very noticeable. I have axle shims on the way now but is there anything else to be looking at?

Got axle shims installed tonight. Problem solved. I didn't remove the CB drop kit. Just to tired at 130am to mess with it. No contractions, so I can wait to tinker with that. Still need to do the front door drop but that will have to wait until next week.
So happy!!!

 

It sounds like you've got it under control. Just mess around with the driveline angles and you should get it figured out.

Have you done the ECGS bushing? Doesn't sound like its your culprit, but it's a good thing to replace anyways.

 

I knew a guy that had a bad vibration and it ended up being from a bad spacer, but he bought it 2nd hand and it may have been warped by the original owner. It's the only case I've heard of and not likely but it is a possibility.

 

The wheel spacers have been on for the last 15000 miles. So most likely not the problem. I checked torque on all the lugs to be sure though.
ECGS bushing hasn't been done. I'll tackle that when I'm out of warranty.
I'm hoping the shim fixes it. I've done the carrier drop kit, and added washers to extend it because several people here said that they had to drop it over half an inch where as the shim is about 5/16th.
I've got a road trip and some Wheeling this weekend so this needs to get solved by Thursday night.
Always when in a pinch.

 

Updates original post. Vibration is gone!!
