Motor and Trans mounts?
Guys appreciate the great advice on this board. This week I have completed the following, Replaced all belts, installed new voltage regulator, rotors, master cyclinder, pads etc. Now its motor mount time. Do I need any special tools?
I want to replace both sides and the trans mount. Am I missing anything that can be done also? Where do I start? |

Before, power wash that area down very well. Be sure the allen caps are clean so that the wrench fits all the way in.
You don't want to risk a stripped bolt here. ![]() You will need a floor jack and a large block of wood to slightly lift the engine just enough to get the mount out/in. While you're in the area of the RF mount, check the condition of the turbo drain tube seal. |

The center bolt on my mounts were IMPOSSIBLE to get off without a 3/8 drive 8mm allen head socket (Craftsman 8mm Hex Bit Socket Sears item #00942678000 Mfr. model #42678), a 3/8 breaker bar and a 2 foot cheater pipe. Do not expect to break the center bolts loose with a T-handle or L-type allen wrench. Neither of those will even reach the bolt head. My passenger side mount was fully collapsed. It was clearly a manufacturer defect. The rubber was fine, it just separated from the metal housing in the center. Replacing it made a WORLD of difference. |

When you do strip out the allen heads... You will need a 3/8" drill bit in a nice, long size (~12"). Home Despot sells them for about $7.
Then, you learn to be much more careful about ensuring the allen socket is inserted fully into the head of the bolt before leaning on the breaker bar. |
