Front Motor Mount Replacement

---

I have a 98 Boxster with 90K and was having some vibrations primarily in 1st gear. I had read that with a bad front motor mount the vibrations are very evident at 3,000 RPM. I did not experience that. With over 90K and no prior replacement, I assumed it was a safe bet that mine needed replacement. I ordered one from Jeff at Sunset, part number 987-375-023-04. The price was $109.48. The 04 was in stock and a newer version ending in 05 would have to be ordered. Both were the same price. I electe

Had a clunking noise coming from what seemed to be the right rear of the car. Initially thought it was the trailing arms. Switched them out (left to right and vice versa), but no relief.

On to motor mount and tranny mounts. Tranny mounts were in exceptional state, considering they must have had 135k on them.

This is what the motor mount looks like.

Glad it fixed the clunking problem.

If your motor mount is more than 8 years old. Just replace it. Your car doesn't shirt hard because we got a lot of power, whatcha is what I thought when dad gave me it. It's an age thing not mileage. And you can't see it until it's out. A lot of people try to take it out squeezing past coolant pipes. It's really not worth it. It would like new coolant any way. Be sure to open the blender vale or you can ruin your tank that is on its way out any way, because they suck. It's a easy job, if you don't try to fight the coolant. Don't take out top mount bolts only loosen them. You will have to drop engine two inches for the lower left bolt to come out. And buy the whole thing, unless you have and are skilled at a press, even then it's worth your time to just get the whole thing. Best place for me to buy it from Maui was Guardian Porsha in Vegas. Duck pelican, just about every part number I compare Guardian is cheeper, and they only have Oem parts. I did but the drive shafts from pelican, because the oem are $700 compared to aftermarket $150.
