need to replace my engine mounts

It wasn’t miles but time for mine. So much weight on them.

 

LOL...but your center of gravity is lower so car is faster!

 

Just did mine recently at 26K miles. Here's the unloaded difference. With the engine compressing it, the difference would be more.

I just had mine done at 22,000 miles.

One side was sagging worse than the other.

 

Just had mine done at 24k

 

28k miles

The 575 mounts are much more robust than the earlier 550/456 mounts, but they still go with time.

AKA better but still not robust

 

I do not understand why they did not design hydraulic mounts.

 

I don't understand why domestic US cars have engine mounts that rarely fail, but Ferrari's fail regularly?

And back in the day, US cars' iron block engines weighed more & vibrated much more than Ferrari's V12's.

And it ain't rocket science to design a more robust mount.....

 

My main guess is small market and little demand to update when the 575 works 'well enough' (aka typically lasts over 10 years vs the 5 years of the earlier 550/456 mounts).

The other issue is the large amplitude 'shock' that the mounts must withstand due to the F1 system vs the low amplitude higher frequency vibrations of classic V8s...maybe? I am grasping at straws here to coverup Ferrari's low-rent design, ha!

 

Omar you're REALLY grasping mate....but you're preaching to the choir.

I love Ferrari but the blunders they make are unforgivable sometimes...... but that's why there's MSW, lol!

 

Every auto maker in the world practices massive stupidity in engineering on every model.

Last I heard the Japanese were subject to far more recalls than anyone else and that is typically an area of really poor engineering on display. And most recalls are for safety.

I have a number of years in German cars. We had a saying "Master Race My Ass".

 

You speak the truth. (Is that statement gonna get me banned like Elon Musk?)

I would never own one other than maybe an older Porsche. IMHO BMW's & Mercedes are goldmines for indy service shops & dealers.

 

BMW and Mercedes are a collection of poor quality parts that are easy to replace. They are very parts intensive and the parts are very high mark up items.

Ferrari is very labor intensive with expensive but very low mark up parts.

Very easy to make a lot of money on the German makes and very low liability to employer for employee mistakes. Ferrari is the inverse.
I had a good mechanic make a simple mistake that cost me the equivalent of a good used Ferrari. Why I have a very low tolerance for being told prices for repair are too high.


No one ever told the Europeans motor mounts should be under shear load, not tension. Mercedes does same. Complete trash.

 

Hard to see but the oil pan is sitting on the steering rack. Its all that prevents it from sitting lower still.

 

Mercedes w124 series mounts last about 5 years, if you are lucky

 

The old ones doesn't seem to feature the integrated shim like the new one? Could the old ones be 192021 instead of 192022 for the new ones?

 

New one looks like a 575 mount which is what I used (see #5) based on a few techs recommendation.

 

Looks like you caught them just in time. These mounts are shot! Now you don't have to worry about them for a while.
