Fix for vibration after lowering?

Hi,
I have a 2010, bought it in March and decided to lower it with H&R springs. As soon as I lowered it I started feeling a small car vibration at 18-20 mph only. Decided to buy new oem Honda axles to see if that would help but it is still there and driving me nuts, I just can't drive a car like this. It doesn't do it all the time but when it does I hate it. This problem seems to be common but some people that are lowered say that they don't have any vibration. So here are my questions.

1. Does anyone know of a fix for this so that I can keep the van lowered? anything I can do to the axles so they don't vibrate? Any shop that works on modifying axles to cure this problem?
2. Does anyone know for sure if the vibration will stop after time after the axles get used to being in whatever position makes them vibrate?
3. If I decide to keep driving it like this (I doubt it), will the vibration damage the transmission?

Thanks for any help or guidance.

The new springs and the unsprung mass (wheels, tires, brakes, suspension parts) form a spring-mass system that has a resonance when you are driving between 18-20 mph and excited by certain road conditions. The only solution is to put your old springs back. Call the spring company and ask.

The strut provides damping to limit the vibration, but not enough to overcome it.

Improper install; Most likely bolt(s) are untorqued or spring is not seated properly. I have my 2006 that is lowered on H&R and there is no vibrational issues at all from 10mph to 30mph and from there all the way up to 105mph, rock solid

1. Axles are not the issue (Save your money), vibrational condition will be improper install or tire balancing (But you'd see tire balancing vibration get severly worse at 80mph+)
2. Reperform the install of springs and ensure all bolts are to proper torque and that spring is seated properly
3. You will have a number of issues occur if you keep driving like this

It will vibrate no matter what, FWD thing. I lowered my 2017 TE at 15k miles and it has the same vibrations. My 2010 is lowered and same problem. Changed axles and vibrations still there.

Nope, this is an install issue not "I lowered my car" issue. Trust me, ive done too many installs and seen too many bad ones to know this

Thanks, I took everything apart 4 times and double checked everything and every bolt torque, I am pretty confident that everything is correct. I even called a place that specializes in axles and as soon as I mentioned that I lower the van the guy right away said and "its vibrating now" he said that lowering can make the axles vibrate at certain speeds. I really don't know what else to do other than putting it back to stock height.

Did you check the wheel alignment after installing the lowering springs?

Camber probably went more negative; other things may have changed just from the R&R.

Even so, I don't see how it could cause the vibration. But checking it may lead to something else.

Also, try the standard fix for vibration: swap the tires front-to-back.

An alignment was done after and I did move the tires. The vibration is not on the steering wheel, its the car that vibrates only from 18-20mph and not everytime. I can feel it from the floor.

Axle alignment and CV joint quality will likely dictate how it performs. Axles can be bad (out of balance) even on new units. Were they OEM or third party? Put a go pro under there and see what’s moving.

Interesting because we've lowered countless vans and SUV here and havent had any issue like that at all lol
The ONLY time we ever heard or saw it was on MINI cooper but that was because those guys slamm the crap out of their cars to the point of needing other work done to even fit the wheels

Only thing I can see is tire wear or pressure MAYBE but never have seen the wheel/chassis vibration

Everything is 100% installed properly. I got temporary relief from changing axles but vibration still there. The lower you go, the more vibration.

Oddity on your car lol, we've never seen it here, changing axle and stil there huh?
Only thing i'd check is wheel bearing itself too, but to do that, pull the axle (Yeah, again) Our bearings over here "passed" the "grab the tire and wiggle it" test but when axle was pulled and hub was spun you could then feel the grittyness of it all. Changed out bearings and ride was on point, but from lowering, no vibration present.
Only other time any sort of wiggle was felt was if I wore the hell out of the inside of the tire, and then it felt like the weakest massage chair in the smurf world, when turning left only

Lowered my 2017 van with 28k miles and it vibrated. On H&R springs. Wtf...
Will this vibration cause future damage to the trans or something?

Vibration from any rotating part puts additional load on the support of that part, be it bearings or bushings or associated parts.

Sooner or later, an unaddressed vibration will cause collateral damage somewhere, in addition of course to annoying the driver in the meantime.
