P 4/5-Enzo Rear Shocks

That's pretty average quality by the sounds of it mate.

I have no doubt you and your guys will come up with an excellent solution.

Please post pics along the way.

 

They probably figured no one would put on that kind of mileage ;-). Atleast not within 25 years.

 

That's pretty common in lesser cars where owners have installed aftermarket suspension upgrades with spherical bearings replacing OEM rubber bushings.

Coilover shock top mounts and sway bar end links are the usual culprits - they ALL develop rattles and clunks. I had a set of Ohlins with spherical bearings in the top mounts - great quality, it took 6 years for them to start getting noisy, but I'm told it is inevitable at some point.

It sounds like the Enzo chassis used similar bearings for greater precision and less flex/slop in the suspension; with the tradeoff that they need to be "serviced" (replaced) at shorter intervals.

 

Same issue with the AMG mods on Mercedes suspensions. Most time they get replaced by a stock rubber bushed unit, LOL

 

Hi Jim,

here we chatted about that topic a bit about 2 Years ago. Last entry that side!

We now have about 24.000 kms or about 15.000 mls on our Enzo. I searched for it so often, but just can´t lokate it. Sometimes i feel something at the rear shokabsorbers, but nothing i can replicate. So far, its just the noise and everything feels solid. No movement in the bushings at the TÜV testing station so far, but need to go there anyway to get it new.

Seems, it was not the best choice from Maranello to use the same bushings as in the F50 on most of the suspension... The we have ZERO problems after lot of track time.

Please pm me with Your solution or share it here!


Give my best to Paolo and Sal (remember him on our California ) Was a nice lunch with you guys in Turin!

 

I am not sure a zero compliance, low rotational friction joint with long lasting road car service qualities exists, at least not better by a large margin. I think the performance/wear ratio is, for now anyway, a trade that those manufacturers have decided is OK.

A long, long time ago a man said "Speed costs money. How fast you want to go?".
I don't think that's changed.

 

Can't complain after 20 years.

it is the age of the rubbers wearing them out. so if you replace with OEM, you will be fine for the next 20!

 

Road cars need rubber bushes ... that will solve it and enable 100,000 miles before next replacement

You can get spherical bearing boots though, but IMO you either do expensive 12k rebuilds or replace with rubber.

Lots of new technology out there since my days of racing in the 60's,70's, and 80's.

Some of the new aerospace plating/coating technology along with adequate shielding/protection can get those heim joints and monoballs to last a little longer.

I agree. Lambo got rid of the heim joint suspension set up with the diablo. I don't think I have ever seen a countach rear suspension not needing some sort of attention. And the parts are damn expensive. Definatly not designed for the long term. Works very well when new however. Practical? Nope..

 

Had an enzo once that was emulating noises in the chassis giving the impression of the control arms slamming the tub when hitting the slightest bump. After a substantial amount of time looking in the wrong direction it turned out to be the brake pads rattling around in the caliper. We fabricated new spring clips to retain the pads and all was well from that point on. Ferrari later issued an updated clip for this same issue.

 

Jim,
any updates?
