i just had my b18c itr put in last week. i noticed a wobble feeling in the pasenger front end between 3000-4000 rpm on slow acceleration. i took it back to the shop where it was installed. the axle was taken out, it turns out the spring seal poped off and kept the axle from seating right, so that was fixed. and everything seemed good till i i got back home, the wobble came back, so i took it back to the shop, the axle was locked in, they had no idea what was causing it. you can not feel the wobble at fast acceleration unless there is a lot of extra weight. but last night it got worst, I was cruzing at 6000rpm about to go threw a turn, i gave it gas and i got a violent shake, any time i try to accelerate fast. the wheels are balanced and everything else seems to be normal. the axles are brand new. I am thinking maybe the axle got warped but i really dont know. i all so had just put in a new wheel bearing on that side a month ago, i did not have this problem witht he old motor. does anyone have any thoughts? thanks

 

Try a different length axle? I'm not too sure..

Thats almost the same thing that happened to me. It was the axle. Make sure to check the boots.

 

it could be flywheel chatter may be ur flywheel has hot spots like rotors have pulsation

 

was your axle not poping in? what did you do, did you have to replace the axle? I all most wander if it the hub, there is squeeky noise i can hear... i dont know, its sketchy though
