Car shaking at 30+ mph
 

When i take my car up to anything above around 30 my car starts to shake really bad. I dont know what it could be and also i hear a popping noise like the noise the CV joint would make if it was going bad but it didnt make that noise when it was on stock ride height. I'm just curious to know what might cause this to do this?

Thanks in advance

Wheel bearing? Have you picked the car off the ground, 10-and-3 test?...What's really bad?? Like, "Oh shit maybe I shouldn't be driving this bad.."..or.."It's just annoying, i'll turn my music up and ignore it bad.."

steps to check or will need to replace:
have you check your tires? could be worn.
Have you done an allingment?
Try tighten the crosssmember bolts or any bolt that is under near the front of the car

how far did u lower it

The shaking is just annoying but the clicking noise is questionable on if i should be driving it or not. Also, i know its not the wheel bearing cause we already replaced it when we did my z6 swap.

My tires are pretty bad and I'm suppose to get an alignment soon but i didnt think not having an alignment could make this much noise?

Right above the tire on the backs and tucking just a little bit in the front. I'll get a pic tomorrow when theres light out.

tomarrow check your cv joint for scraches where it might hit and your tierods for your stearing you might have to clearince them

Also check wheel balance on the front tires, see if your wheel weights are still on and have them rebalanced.

I had a bad shake on my rex at certain speeds and it turned out i just needed my wheels rebalanced. Could just be as simple as that.

loose suspension parts also theres supposed to be a upper an lower bushing on the strut one gose on the under side one goes on the upper it makes your car feel weird make weir noises if ones missing sometimes you wont notice if you didnt put it in

Re: Car shaking at 30+ mph
 

So the car drove fine before you lowered it and as soon as you lowered it the shaking/noise started, correct? If so, you may have an axle that is too long. Especially if they are not the OEM axles. At the stock ride height there would be no issues, but when lowered the clearance of the inside cv joint is now greatly decreased. Had this same exact problem and turned out the "rebuilt" axle that was installed in the car was actually the length of an EG(too long).
Good luck.

EF sedan, sorry about that. Forgot to put it up.

Yea, my brother works at honda so im waiting for him to have free time so he could do my alignment and everything.

I'll double check to see if all the stuff is there today when it cools down.

This makes a lot of sense because we did do a z6 swap and were unsure about which axle to use and i think we bought one for the EG chassis.

I just bought an EF sedan and it was started shaking at 45,mph by 65 it was really bad almost not safe. Rebalancing fixed the issue for me, but mine isn't lowered.

:o

Re: Car shaking at 30+ mph
 

Yea, my brothers rebalancing my wheels for me tomorrow or this weekend for sure. I'm going to try this before spending money on another axle.
