the point of this post is gettin glost in all the slang and halfway information being shared
outrider, all AE/EE1** mounts are interchangeable except for differences in the top tranny mount, in which case many ppl end up pressing out the bushing in their existing mount and pressing in a good one with no problems whatsoever.
sometimes the back and front mounts have a rubber protrusion which acts like a harmonic dampener, in case the mounts fail, you won't vibrate the bejeezuz out of it before you replace it
now, you can pay out your nose by TTTL for OEM mounts or u can buy proper Japanese mounts (not the Taiwan crap) at any reputable parts place...they'll tell you which it is so you decide what u want
now come the questions...
is the vibration isolated in the steering or does the whole car vibrate?
if it's in the steering alone:
are your steering rack and coupling secured? (should be only one since the DX AFAIK doesn't come with an adjustable height steering column..other models will some with two couplings if they have that option)
check for play in the steering column itself...right now I have a worn plastic bushing in mine that causes a very small bit of up-down play and vibration..I'm still yet to sort out if the bushing itself can be replaced or if the entire column needs to be replaced..it's not that expensive to replace the column anyway, so I'll make a day of it and just do that once I clear a day to do it
if it's the whole car:
were the mounts fastened securely?
how's your idle speed? (an unusually low idle will cause the car to vibrate excessively)
is anything loose or rubbing under the hood?
u need to assess the situation fully before u ask
hope this helps
