front motor mount
Changed the front motormount on the 04 boxster S today at 58K miles. Some cracking of the rubber at the edges, but not a lot. don't know if it was bad enough to notice any difference, it is a tiptronic. At least now I know it is good. Not a real bad job since I have a lift and good supply of tools. Would have been considerably more difficult without the lift. Took about an hour and a half, taking my time and cleaning everything up well.

Two back ones OK then?

Yes, in nice shape. The tiptronic trans may not put as much strain on mounts as the six speed. I really had not noticed any symptoms of a bad mount, but was just preparing for a cross country rally of about 7K miles and wanted to head off any potential problems. Now a water pump, thermostat and belt, new tires and oil change.

Did you get the whole mount or just the bushing?

A quick question. What are signs of the front motor mount going off?

Noticed the other day that I can feel some "shifting" in the gear shift lever when accelerating and sometimes when letting off the accelerator. Not bad enough to call it a "jerking" of the gear shifter, and I really almost need to be intentionally "less smooth" with the accelerator to get it to cause the gear shifter to move. So - how much "shifting / jerking" is normal and when do we start looking at the front motor mount (or transmission mounts?). Thanks! |

I changed mine a couple weeks back, did not notice really anything that pointed to the motor mount but was under the car doing some preventive work and thought I might as well do it as I had just over 65k.
Let me say one thing I can now have a nice conversation in the car, and do notice shifting seems better but as they wear over time I guess I just got use to the extra noise vibration. After looking at it I am so glad I replaced when I did! :eek: http://986forum.com/forums/uploads01...1399572919.jpg |
I think someone smart like Pedro wrote that the front motor mount from the factory craps out at about 40-50k miles and that's all one should expect from it.
Now upgrading to something that will last longer will also cause more vibration... Porsche engineers their parts for performance AND comfort. |
I've replaced mounts on three different Boxsters over the last few years. Shifting improves, idle is smoother and no harmonic vibration at ~3K rpm are the main things that get fixed.
I did swap just a bushing in the mount one time and it wasn't very hard to do. The bushing as $39. Prior to removing the old bushing, I marked it and its position in the mount. I then sat the new bushing on top of the old, alingned the holes and marked it as well. I put my motor mount in a vice and used a hack saw to break up the old mount and pull it out. It was quite easy to do by hand. I then took my new (Frozen) bushing, alinged the holes and pressed it in using the vice. It when right in without any drama. |
