Whiteline Roll Center Adjust carnage.....
Ok, a little back story, I bought this car a little more than a month ago. It was tracked, road raced (by a respected member of the community), but well maintained. There have been a few issues that I've been trying to resolve and this is one of them. I started hearing some squeaks come from the front of the car when turning at low speed so I decided to inspect it. This is what I found:
Question, how did this happen? And what can I do to prevent it from happening again? Obviously I have to get a new lower ball joint, from whiteline presumably as OEM lower ball joints aren't available. One thing to take note is that these were installed summer of last year.
I imagine the alignment is off by a good bit due to this issue as well. The tire wear would certainly indicate so.
Also, these whiteline boots don't seem to hold up. On the tie rod end you can see the boot dry rotting pretty badly already. Again, these are about a year old and have been through one winter.

Seems like the boot tore and lost it's grease on the top pic (ball joint most likely has problems now). Other's have stated that the stock boot fits just fine (MR455070), might hold up better than white line provides.

Yeah, your rotor heatshield is missing. After a cool down lap, driving through the pits, getting out and then using a laser temp gauge, my discs were still over 600F deg.

Thanks for the help guys. These details are all quite new to me as this is my first EVO. I'll contact Whiteline first thing after the holiday. Do you think the car is safe to drive? There are no clunks, just a squeak here and there. As far as the heat shield, the car has the AMS brake ducts installed, would these eliminate the possibility of running the stock heat shields? Thanks again.

G’day everyone,
black95tt, understand your concern and I wouldn’t be happy about driving without a fresh boot on that ball joint for too long.
Its a tough one to deal with as our original design kit for this application used high temp silicon for the boot material in response to issues with OE or stock boots. The silicon has a high temp resistance compared with stock however it’s a little fragile and we were getting complaints about tearing when fitting etc.
We then changed over to a higher spec synthetic rubber that has a higher operating temp resistance than stock and is much more durable than silicon. That is our current material spec but unfortunately the design of the EVO front makes this a high heat stress application when racing and particularly when removing stock heat shields.
Jeff_Jeske, you’re spot on with your comments and we experienced same when preparing our EVO 8 development car back in 2004. The braking performance suffered if the heat shields were left on and most EVO’s used a cloth (Kevlar weave or similar) shield wired on to the outside of the tier rod and ball joint boot. I believe this is still used on racing EVO’s to this day.
No doubt a brake ducting solution would work well here. Let us know is there is anything more we can do.
Cheers

exactly what I was going to say. Wrapping a heat reflector around the boot would be a good idea. If you get a chance to peek under some ferraris or maseratis, they have a reflective heat shield wrapped around all the balljoints. might not be a bad idea for the evo.

the car would be ok to drive. the balljoint is already ruined, your not going to make it worse. I would get it replaced asap. If you put it off to get it fixed it might be bad.
