i've been driving my 98 hx coupe for about 2-3 years on lowering springs. last summer i replaced the stock shocks with agx shocks/struts. i have an ingalls camber kit for the front and rear and the springs are made by sprint.

question 1: when i accelerate my wheel jerks to the right and when i brake it jerks to the left. i think that it is the lca, but i dont know which one.

question 2: i smacked a curb a while back hitting my front right wheel hard. Now there is a slight vibration at speed (around 60 or 70 mph) and the car shakes violently once i apply the brake at that speed. at normal speeds (30 or 40) there is no real vibration when braking or driving. when i am lightly applying the brake at a slow speed i can feel the car pulsing, like the rotor is warped. i dont think that this would happen from hitting a curb, but someone out there might know better.

question 3: the inside of the tire (the sidewall facing the car) is warmer after driving than the outside on all tires except the left rear.

question 4: sort of related to question one. there is a popping noise that comes from my front left wheel well when braking or turning. this noise happens fairly regularly when braking and not often when turning. also, my car is starting to creak when driving over bumps, more so when it was cold out than now. it has been a while since the bushings have been greased, and i was considering replacing them, if this is even what is causing the creaking. good idea?

thanks in advance.

 

The majority of your issues (possibly all of them) sound like they could be related to your curbing the car, possibly bending the LCA and/or strut arm. (thats what I call it, for the life of me I cannot find the proper name for it, but its the arm that runs from the hub and connects to the UCA). Depending on how its bent, it could affect your camber or toe or caster or all 3, which would explain the erratic handling behavior under braking and acceleration and at speed. Take it to a shop you trust and have them take a look at the corner that was impacted, and see if they can't find anything bent. You can do it on your own as well. Possibly, your alignment was just messed up on impact, and a simple alignment will get you back on track.
THe popping could be a bad lower ball joint. If your bushings are shot, then its not a bad idea to replace them although its not something you can do in your garage.

 

i agree with most of what you said, but how would banging one wheel into a curb affect the camber/toe/caster on the other three wheels?

the alignment isn't really bad. before i smacked the curb the car would pull slightly to the right, but not enough to get it realigned. afterward the alignment didn't seem to change...

i am going to take it to a shop soon, but i figured i would get a heads-up on what could be the problem before finding one.

 

What I meant was that the impact could affect camber, caster, toe, or any combination of the three.
If something is bent, you know the shop likely won't be able to get alignment back within spec perfectly. It might be possible they did the best they could, but since cars are pretty sensitive to changes in alignment, it won't take much to cause handling and wear issues.
