1998 Corolla Mount Alignment Problem

By ship_reck, March 30, 2010

i have a 1998 corolla with 209K on the ODO. recently been having rough idle and vibration issues, so i've replaced the 4 mounts (2 engine and 2 transmission), and am now having an issue with the side transmission mount (on driver's side, directly under the air filter housing ).

 

no matter how i jack-up and try to shift the engine position ( with all mount thru bolts loose), when i torque down the bolts and remove the jacks, the engine returns to a position in which the yoke bracket on the transmission is touching the metal portion of the transmission mount. the engine/transmission appear to be shifted back, such that the mount isn't centered with the transmission yoke bracket. this positioning/interference is causing a chattering noise and vibration (not as bad as before), as well as a clunk at start.

 

anybody have any advice on getting the proper engine alignment after replacing motor and transmission mounts? maybe something i'm not disconnecting or a technique i haven't tried? any advice is greatly appreciated.

You might try loosening all of the mounting bolts (not just thru bolts), dropping the engine into its "home" position and then tightening them all.

tried that last night, to no avail. looks like the problem might lie in using aftermarker (anchor) mounts. is there a good place to order oem parts online? my local dealer wants $450 + tax....

looks like the aftermarket mount i purchased was for a 3-speed auto, i've got an LE corolla w/a 4-speed auto.

Yeah, that will probably do it.
