Re: Rear axle hop

Seems you have been blessed both in your work and home life. Never been to NL. Looks beautiful on Rick Steves. Max is the best ever and I'm old enough to have seen Mario, Niki and James race. Yes, Metalastic and two-piece bushes work differently if you don't grease them. Jag used to put slight knurl...

Re: Rear axle hop

Huib, Mine's an 820.436. There's six leaves. Fig 48 in the manual shows five; one full length at top. Mine has 2 full length on top. The rear shackle block is 10 deg from vertical (top-fwd, bot-aft). Is there a spec? I'll try loosening the center bolts and re-tightening at zero camber if the weight ...

Re: Rear axle hop

Huib, Thanks for the info dump. You really pointed me in the right direction. I've determined the following: The spring position under load (measured from the bump rubber) is 8.5 cm. Spec is 5cm, plus the 2 cm you said is added by Decarbons, equals 7cm. So at some point, maybe when Decarbons were un...

Re: Rear axle hop

Huib, Thinking on this more; given the volume change from full bump to full rebound in a Decarbon monotube, the gas is compressed a lot. This would explain why Lancia mounted the shocks at such a steep angle, which has been puzzling me (52 deg from vertical at full bump). A twin tube adjustable like...

Re: Rear axle hop

Huib, That's how I want my car to be! I read the write-up on your website and it sounds as if the DeCarbon's provide additional springing as well as damping? If Lancia intended the shocks to supplement the springs, then twin tube would definitely be inferior. Will they change the ride height? Can yo...

Re: Rear axle hop

The shocks seem about the same in bump and rebound. Working but not very stiff. Someone did not use shoulder bolts- threads a bit hammered. Rear tires over-inflated; 31 psi hot. Manual says 28.6. Springs and shackle blocks painted over, so I'll have to pull them and inspect/replace rubbers. I did le...

Re: Rear axle hop

On moderate speed curves the rear end hops sideways over bumps. It's worse over high frequency small displacement bumps (like expansion joints) than low frequency large displacement bumps. The wheels are definitely losing contact w/ road surface. On washboard surfaces it's a handful. Unable to deter...

Rear axle hop

My 2000HF has too much lateral bump steer. Rear shocks and bushings in good shape. Shocks are Tecno Suspension circa 2018. Not sure what to do to keep the rear wheels on the ground. I've posted on other Flavia/2000 forums but have not heard back. Any advice appreciated. I'm also posting this on the ...
