F45 Shocks
My mistress and I are rapidy approaching the 30,000 mile mark (actually, she's approaching the 30,000 mile mark, I passed that mark decades ago :lol: ). Does anyone in these parts have any idea how long the F45 shocks last? How do I tell if they need replacement--leaks, ride, control???
As always, thank you in advance! :cheers:

Re: F45 Shocks (Chris18tx)
I have 73K on mine, no leaks or codes. Swapping springs and shocks (if springs don't fix bottoming) soon, as it will bottom too often (lowered). The shocks still work, but I think they have had to degrade some. The springs are probably sagged out. I guess best way is to ride in a newer one, as changes like this happen so gradually, it's hard to notice. Rode in an 02 Z06 and it was definitely better over speed bumps.

Re: F45 Shocks (decay)
35K and in touring mode I get a ping sound from both of the front shocks or springs going over a bump. In Sport or Perf mode it goes away. I drive in Sport cause the ping is annoying. Ne1 else have this problem?

Re: F45 Shocks (Purerock105)
Well, thanks to everyone.
No, I don't have leaks or codes related to the suspension.
However, I think my butt is still too low. The previous owner had lowered the car, and I paid to have it "unlowered". But, it still sits lower at the rear than any other C5 I park next to.
I've decided to leave it in SPORT, unless I get wild and crazy and go to PERF. The TOUR setting is one I only use on the WONDERFUL stretch of I-65 in KY on the way the NCM.

Re: F45 Shocks (decay)
89,000 miles and the shocks are useless in touring mode. Getting worse in Performance. I think it is a combination of old springs and old shocks. I will be contacting the Bilstein Service Center about rebuilt shocks as new one are big $$$$$$.

Re: F45 Shocks (gonbad)
Gonbad,
Do a search, Someone tried Bilstein and was told that they didn't make the shocks on 97 up C5's. They said they were made by ??? and they can't do anything with them.
I don't think anyone found out were to get them rebuilt at yet.

Re: F45 Shocks (gonbad)
Oh well. I was going to replace the springs with Z51 units as I already have the Z51 bars. Plus I need to probably replace all the bushings as well. I will probably go urethane as the car does see road course duty a few times a year.

Re: F45 Shocks (decay)
1. To test the shock, push down on the corner of the car and observe the rebound characteristics. A corner with a bad shock will bounce more than a corner with a good shock.
2. The F45 shocks are made by Delco. The GM Parts Direct part number is 22064825. Goes for about $290 from them, or $600 (!!!!) from a dealer.
