Hello All! I have a 90 ef sedan. Engine is, 2000 gs-R motor, 94 LS tranny, new ebay motor mounts, and new(not rebult) autozone 91 integra axels. I have 2 issues(I think). I installed the motor mounts and axels. I was having alot of engine vibration in the cab, and I thought it was from the engine mounts. The car "had" 92-95 civic b-series mounts when I purchased it. It had clanking axels with torn boots also. I replace the mounts and axels. Car handles great now. But the vibration is worse. I am thinking the flywheel and/or clutch are out of balance. Reason being is the previous owner told me the cluch will need to be replaced soon because he put a used one in. Will this vibration be caused by a bad clutch/flywheel? I notice most of the vibration on the front of the engine(driver side). Another note, I noticed the previous owner chizzled the outer pulley run lip off the crank pulley. I guess he could not get the engine to fit. Could this cause a crank imballance? Also before anyone suggest I check the alternator clearance, I made sure to notch the driver side frame(this was not done by previous owner). Second issue. I have been driving the car with new mounts and axels for a month. I notice that in 2nd & 3rd gear the engine seems to be shaking. I am thinking I may have installed the wrong axels. The original axels were for abs(dont know if that makes a difference). They may have been 94 axels and not 91. But I could not tell the difference when I compaired old/new. Anyone have any ideas? I apologize for the long story. I just want to make sure I get all details in one post.
