well, i have a 91 crx with a 1st gen b16a. my problem is that it shakes like theres no tomarrow. i just put new rota's on & balanced them, so its not that. the shop that put my axles in said that there was a little play in the intermiadte shaft but shouldn't be a big problem. on the left side (if in car) i have a integra axle(90-93) but on the other side i have a del sol axle. the car seems to be thumping really bad when making right turns, but if i make a left turn the car is smooth, it shakes pretty bad when driving straight . hope i explained myself ok.
help please!!! i havn't driving my crx for a year now , and i'm sooo close!

 

sounds like your mismatched axles but I am not too sure about that it seems like you have something either to lose. perhaps the axle on your right is shorter and is moving around a bit giving you the extreme shakes. Another thing is the wheels are they balanced also? If not then try that. Are your shocks good and do you have a good aligment???
