Default Bilstien rebuild.

Do I send them to Bilstien for rebuild and moracca valving or whatever you call it! I just don't know about the KYB's that are on it. I still say they are to soft.

Yes they go to Bilstein.. I would give them a call to see if it goes to a specific Dept..

Also is you are thinking of Coilovers, get them grooved while being rebuilt

Are the KYB's FX3 controlled?

Don't know if mine will stay like it is but have a couple hundred miles on poly control arm bushings. I could hardly bounce the front of the car after installing them, just checked and they have loosened up some, still solid but can bounce it by standing on engine now, but anyway, the shocks I thought were way too loose when set to the first setting which made me think they were probably tired but after putting in these bushings it's really hard to tell a difference in the three settings unless on a really rough road. It handles really good now, so don't really know if it's the bushings or the new alignment, think there was too much toe in before. But it takes rough roads a lot better with no loose feeling or shuddering as if the shocks were replaced. Now the back bounces without the front but is ok with FX3 on high.



If your bushings are original the poly's might be worth considering. Bushings are only $100 If you do the work. Or more if you want the offset lower bushings for more camber.They do squeak, but can't hear it while driving.

No they're not FX3 controlled. They're just dummy shocks. I've got some other issues that I already know about. I know I've got three bad wheel bearings. I don't get a tick I get a squeak,squeak,squeak. Although bearly noticable its there. The faster I go the faster it squeaks. But I've had that ever since I've owned the car.
Every saturday morning just like a ritual I would get up at 6:00am and take her up to top speed to blow out the pipes and make sure the secondaries stay healthy. Just look at the avitar. But in a really short amount of time the handling deteriorated to the point that I won't take it passed 130mph for fear of my life. The shaking and rattling is to much to go any faster.
I've replaced all the ujoints with new Spicers. That didn't solve the problem. I've replaced the rear leaf spring which is stiffer. Still didn't solve the problem. Found a cracked bushing in the passengers side upper a-arm replaced the whole a-arm. That didn't solve the problem. Got a 4 point alignment done. That didn't solve the problem.
I was told by another fellow ZR-1 owner that one time his whole steering rack was loose and he took it to this place in town and for $150 they rebuilt and rebushinged it. But when I grab on my tie rods or any of my suspension components and jerk them back and fouth they are solid.
So I'm left with a few conclusions. Either my wheel bearings have wore out to the point that taking it up to high speeds have helped accelerate their decay or the fact that my front tires are old and hard and when the car is jacked up and I spin them by hand they look a little lopsided. But my brand new rear tires look the same way when they spin. So go figure. I'd like to fix the cause of the problem first then throw money at rebuilt bilsteins. I'll figure it out I'm sure. One thing I've learned is that if you have slight suspension wear! Then taking it up to high speed it will just brake that bad component down even quicker.
One my 68 mustang its very easy to see whats wrong right away with the suspension. On this thing it's not. The suspension is far more complex.
I just havent seen alot of threads on suspension issues. It's usually an electrical problem or secondary/fuel delivery/idle problems/no start/overheating ect. You know,the usual stuff. But not alot on suspension issues.I don't want to throw money at stuff that's not the cause of the problem. Because it's just not obvious to me what it is. But I do have the old Bilsteins in a box. And even though they are not going to solve my suspension issue, I still want to send them off for a rebuild.

Can't blame you for throwing money at it.

Usually the bearings have a noticeable slop in them if bad, or the disc will scrape on the caliper bracket with hard turns. had one though that was no slop, took it to the track and it failed and took out the abs sensor with it and it still didn't vibrate at 100, handled really scarey loose like a truck steering. But if there squeaking, there really bad.

I wouldn't recomend it but I would probably try jack up the back and support the rear as if weighted to keep the rear universals at a good angle and give it a spin to rule out the front.

Your tires look lopsided? I've spun wheels with tires off and on with a support right next to inner and outer sides of wheels and tires to check for out of round and they all been surprisingly straight, almost perfect, not like my walmart tires on the daily driver.(except for some ebay wheels, but haven't tried them yet).

Have you had the road force type wheel balancer used on them, they do a really good job and if something is not straight it will let you know?

Even if your suspension was loose on a smooth road at high speed I would think it should be smooth.(unless you have bad bearings)

Have the drive shaft and half shafts been balanced, might show up a bent one?


I need to move to wherever you are if 130 can be done everyday and more if it isn't shaking

Corvette recycling has ac delco bearing good price but they might be out of the front ones.

Yeah Bobby! I've been told by both Bradley Taylor and Lee that they strongly feel it's my wheel bearings. They were both here in person. And when I told them about it the first thing they did was put one hand on the top and one hand on the bottom of each tire and wiggle them and you could see they were loose. They are not suppose to be loose at all. Both rears are like that and the passenger front tire is to. The toll roads early in the morning are empty. If you think 179mph is fast I have a couple of freinds with pumped up Zo6's that have driven over 200mph on those roads. They are a little younger and more crazy than I am.

That's even cheaper than I was thinking since I haven't done the rear yet, probably save that for next winter though. Although the lower front offset wasn't cheap as compared to the standard kits.
