i replaced a rear hydro mount with a solid one, figuring it would be a similar situation as the front mount. i dont know about actual vibration (i wasnt really getting any to begin with...changing the mounts was a "while you're in there" thing) but the solid mount *definately* allowed for more engine movement. it was a noticible amount, whether you were revving the engine or just grabbing it by the manifold and pushing/pulling on it.
was it designed to last longer? i have no doubt. visual inspection of various used rear mounts will show that. was it designed to have less vibration? probably. like i said, i didnt notice any difference in the vibration department, but i would imaging the hydro mount has much better damping qualities to it. the fatal flaw in the front hydro mount is the fact that it, by nature, is getting ripped aprart every time the engine moves. all the other mounts (including the solid front mount) are compressed, and are less suceptible to fatigue. funny story...when i bought my 92 in may, i noticed a HELL of alot of engine flex. the front mount was pooped. i tried to install my 6 month old solid mount from my 87 parts car, but the threads were screwed up and so was the bracket, and i didnt have tome to get it welded properly. so a buddy scored a hydro mount from the dealer he works at (one of those "lying in the back corner" deals) and i installed that. its okay. definately better than the other one. and hell, it was free. okay...so when i took the old mount out and turned it upside down, all of the fluid poured out of it. (i guess it coulda been rainwater too) just flipping that mount would send the stud out about an inch. yikes! ben randolph 92 16v gti alpacino wrote: > > actually this is sort of true but the way they are designed will not see any > difference what so ever in the vibration department nad they indeed do last > much longer. > -----Original Message----- > From: Ben Randolph <[email protected]> > >FYI, the hydraulic rear mount is stiffer than the solid one. _____________ List Sponsor: http://www.netsville.com To remove yourself from this list, send mail to [email protected] with 'unsubscribe a2_16v' in the body of your message See us on the web at http://www.a2-16v.com Visit the 16V Homepage at http://www.gti16v.org
