Vibrations

I had a RC 6 inch Vertex lift installed on my 2017 Tacoma but the rear sags, so I installed a Supreme add a leaf 1.5 " - 2 " installed.
The rear now sits at about 1.5 "but it has a slight rake to it.

The problem I'm having now is some vibrations most noticeable when going up a slight incline.
My research on YouTube recommends a spacer for the drive shaft bearing.

I have 3 spacers ( on each side ) already mounted on the carrier bearing that came with the lift kit.

My question is: Can I add another spacer to make it 4 spacers total ?

I appreciate any advice, Thanks !

 

I don't see why not if your bolts are long enough. Could make your situation worse though. Read through this thread maybe it'll help you solve your issue

I'd put a camera back there and check to see what the axle wrap looks like. Spacers will help some of the vibration but if you're changing the leaf spring dynamics you're probably gonna find a whole lot of axle wrap. With a bigass lift, you're gonna need some kind of traction bar setup to keep the rear under control.

Firmer add a leaf if anything will bump up rear wheel hop and wrap. I bet that's what you're feeling.
