Vibe after Lift - ECGS Bushing Didn’t Fix It

Road force balancing tomorrow AM. It’s a shot in the dark, but I’ve wasted more money than that, so far.

 

I need to find a shop near me that does RF balancing... it truely does get a more accurate balance on a tire.. used to work at a shop that had one of these Hunter 2000 machines.. it could easily detect out of round rims, bad tires, and correct some wobbles that were hard to find or correct on a regular machine.

hopefully it solves, or reduces your problem.. hoping I can get this done on my rig soon.. lots of jeep off road guys swear by bead shot.... 6-8oz of beads to correct a 33-35" tire imbalance.. but I am not a fan...

 

If you’ve got a Discount Tire chain store near you, they do it. $20 a wheel.

 

I have ione in Rockland, just not sure they do RF... there is a shop in Camden that advertises that they do road force balancing...

 

Did you install the lift or paid someone? If you did it yourself take them out and see what happens. If you paid someone I can see the resistance to keep trying to minimize expenses. I'm with you on the fact that it goes away in 4HI and that tires and most things can't be it. I've always been a proponent of keeping the stock Rake vs leveling it, I just feel that geometrically it is the way to go. Don't know much about the RC lift but the rear lift blocks should be tapered for sure. Good luck $.02

 

I was going to mention this, I had brand new Hankook Dynopros I put on myself, Had a death wobble at 50-70 mph Thought it was my wheel spacers on factory rims, did a road force and at 55lbs that was the cause. Warranty out the tires and the next set was just as bad, then went with a Diff brand.... Don't leave the shop with them being more than 25lbs or you will never get rid of it.

 

You may be right. Yeah, I paid for the install—thus the stubborn refusal to stop throwing more money at it, LOL.

 

So, you’re saying yours were overinflated and that was the cause?

 

Update: Tire shop said road force balancing wouldn’t do a damn thing, based on the description of the problem. I’m just taking the lift kit off. The only other thing I can think of to do is pull the spacers and put in longer struts in the front, but that’ll be another $350. I’m out. F this thing.

 

sorry bro, could be the lift, and no UCA's? I know approaching 3" lift the tacoma steering seems flat, and can cause alignment vibes/death-wobble. I went with High castor UCA's from JBAoffroad. this puts back some of the steering feel. and return to center.. but I still have these low vibes (I believe to be a combination of tire balance (wieghts got knocked off), or the rear pinion angle, but I have yet to get underneath my truck with an angle finder to check it.

 

OK, boys, looks like I’m in it for the long haul. Gonna leave this damnable lift on it and f’ing figure this bitch out. Any more ideas?

 

You really think UCA’s could cause a vibe/noise that disappears in 4WD?

 

Dude it’s gotta be the bushing trust me

 

With a 2 inch lift in front end the cv needle bearings will hum. Replace with bushings. I think they around 60 bucks but labor will cost you.

 

I would have bought a new bushing.

 

You guys did read that he has already done the ECG needle replacement, right?

 

If ECGS bushing didnt help id try the next steps: Carrier bearing drop and axle shims should help

If those mods dont help, then tire misalignment or unbalanced tires would be my guess

 

Even after my ECGS replacement there was still a vibe, just less.

It's 100% the spacer lift, its too much strain, either live with it, or install a 2" lift.

 

I think we can put to rest the ‘bushing was installed wrong’ theory. According to Will at ECGS, “[t]he only way to install it incorrectly is to drive it in too far in which it would contact the spider gears inside of the carrier.” When I asked what symptoms that would cause, he replied, “Not what you're describing.”

So, unless the shop didn’t install the bushing AT ALL (which I guess we can’t eliminate without having another shop pull the CV again), then the vibe is something else.

I can see what Bishop84 is saying about the bushing reducing but not eliminating the vibe, but in my case it didn’t change it one iota.

I’m thinking about just replacing the spacers with lifted struts. Worse case scenario, I’m out $350 and that doesn’t fix it. It’s cheaper than changing whole lift out for a 2” lift. Anyway, still kicking that around.

 

Following along for the outcome... hope u get this figured out.
