I get a vibration during braking mainly around 40-60 on heavy braking. recently i replaces my strut nuts as they were old and one was more or less strip. but since i did that the car seems floaty now and the braking vibration has gotten worse. struts are bilsteins less than a year old control arms same deal and strut mounts and spring seats. strut mounts and bilsteins i went for the cheaper ones at the time because thats all i could afford.

 

Did you get an alignment after that suspension work? Get your rotors turned?

 

brakes are also less then a year. and no havent gotten an alignment yet

 

If you didn't seat the control arms before you torqued them down, they may already be bad. Jack the car and see if you get any control arm movement at the frame bushings.

 

what do you mean by seat? i checked for movement the other day and it all seemed nice and tight

 

what do you mean by seat? i put the control arm in the slots ran the bolts thru hooked it to the knuckle then bolted them down

 

Had a similar issue. Replaced the lower control arms as the ball joints were shot. Fixed the problem

 

I have not experienced this myself but this is how it was explained to me. I was also told this is in the repair mainual as "how to correctly do the job".

When you jack the car to remove the control arm, as you well know, the wheel drops as the car raises, causing the suspension to be extended. This is an un-natural position. So, when you install the new control arm, it will be sagging. If you torque the arm bolts (against the frame) while the arm is sagging, they are being positioned in the extened position. When you let the car down (job done), the bushing will be twisted and have torque on them. This continued torque will cause pre-mature failure of the bushing. So, what you are suppose to do is this... Install the arm but DO NOT torque it. Install the wheel and lower the car to the ground or raise the wheel to it's natural resting position, THEN TORQUE the control arm so that it is secure in it's natural resting position. Thus turqueing the part on in it's SEAT position.

When I do mine (soon), I plan to put the control arm on, not tighten the (frame bolts) just snug them. Then drive around the block and drive the car on ramps, then torque them down.

Hope that makes sense.

 

ah makes sense, im going to check them again, i know they're the cheaper ones but hopefully not bad after a year..lol

 

i also hear a creaking from the drivers front tower when turning in a parking lot, and once and while hear a knock when turning at around like 10-15 mph

 

Correction, it's called PRE-LOAD not SEAT.

As for the creaking, I'm pretty sure I've read that it's your strut seat that causes that noise.

 

which are also less than a year old but are oem lol, my suspension hates me

 

Were the strut mounts replaced with the spring seats?

 

yes they were

 

Upper strut mount going out ??

 

the upper strut mounts and spring seats and struts and control arms were all replaced around the same time.
