hey guys I have a 2014 acura tl fwd 3.5.

recently I've put some coil overs on that car and dropped it (its sitting pretty low) but for some reason from the moment I lowered the car I noticed that from 10-40 mph the car seems to shake. now the car shakes but the steering wheel does not. I've gotten an alignment from that time everything is dialed up and I've also mounted and balanced brand new tires with brand new rims and shaking still consists. it only does it from around that mph because if I'm crusing 50+ mph I won't feel a thing. btw it is also only under acceleration. my only other theory at the moment is that the car is sitting to low and the cv axle is pushing it outwards at low speeds ( I've had this problem in other lowered cars ). I'm trying to find out if any of you guys have ran into this problem before?

thanks a lot for the help!

 

things are not properly torqued. also are you on stock wheels and stock lug nuts?

 

vibration on acceleration is a symptom of a bad axle. You should have both replaced with raxles. Lowering the car puts a LOT more stress on ball joints, axles joints and CV joints. They are designed to work/mesh at a certain angle and lowering the car throws it out of this range. Being out of range causes the premature wear or allows you to feel the worn parts as they have shifted.

Don't buy OEM axles otherwise the same issue will happen, autozone/local ones are junk. You can look into insane-shafts but the 3G TL guys love raxles.
