Default Help!! Broken LG GT2 coilover - PICS

Hi All,
I had noticed my car making a weird knocking type noise from the front right suspension, especially when going over bumps. The car appeared normal and upon quick inspection I didn't see anything abnormal, so I drove home. The knocking was still present, getting louder over bumps. I got home, suspecting possibly a loose sway bar, however after removing the wheel and lifting the car, this is what I found...

Any ideas on this? The coilers are probably 4 or 5 years old, I cannot remember exactly when I bought them or from which vendor. They have given me zero problems until this point so I am hoping they can be replaced by LG. Any thoughts or recommendations? I will get more pics once I get them off the car

I would pull that coilover off and see if it can't be reattached, most likely not but contact LG and see if they have any thoughts?

Thanks for the help! I did just that and called LG. Just sent them pictures, hoping they can get it taken care of. Here are the pics I took after pulling it off.

Wow, that is really not confidence inspiring in LG. I've heard of the lower quality coilovers breaking when they hit curbs, but never during normal driving. You sure you or someone else driving your car didn't hit a curb?

I'm curious to see what LG has to say about this. I was strongly considering their coils

Follow-up? What's happening on this? How is LG handling this?

Because they are LG coilovers.

Coilover guys, I have a question. Before changing to coilovers the mounting point on the frame only carried the weight/ force generated by the movement of the shock absorber. With the coilovers each point is loaded about one quarter of the weight of the car, give or take. I guess it works, but how? In addition the lower shock bolts are now weight loaded as well. Lost in space, or at least Ohio.

TIA.

LG claims it will be fine. Here is a video of them testing their coilovers for extreme impacts.

It's their problem because coilovers, even 5 year old ones, are not supposed to break like that. Even cheap **** like Fortune Auto or Stance or Megan don't just randomly break like that after 5 years unless you hit a curb or something. So obviously that's disturbing. Do you seriously get new coilovers every few years or something? It's absurd to not expect better quality than that.

Any updates?

Dude, take it easy on LG Motorsports. If there were a quality or manufacturing issue it would have broke [U]long ago[U]. There is more to this scenario than what meets the eye. Like you said, shocks don't just break unless it is hammered beyond its threshold or as you say "hit a curb". Study the photographs a little closer. What do you think caused the damage to that rubber cushion damper? This shock has been bottomed out... hard... more than once! I would be interested to see what the rubber cushions in the other shocks look like.

I'd do what brandon suggest after thinking about what big chief said above: call and talk w. LG, show them the pics. Let's face it if you abuse something (you or the prior owner), nothing is gonna last forever.* Is it a defect-maybe but I doubt it after that long on the car. I say, talk it over and see what they will do for you. In the past they've been fair with owners of their products.

* I hit an expansion strip that was raised metal!!!! in CT. I hit it so hard, at speed, that I thought I'd ruined all four wheels and popped out bulges in the tires---would not have been surprised at all. I got lucky, didn't happen. But if it had, I would have known exactly where and when. Take a look at C7 Gen and Z06 threads re stock wheels folding up on them; a couple guys had all four go at the same time. Some claim they didn't do it; maybe so, maybe not. But theirs happen both on and off the track, and usually within first few thou miles.

Really? So everything that *can* break should break in the first, what, 1 or 2 months? I think his point is that LG has gone out of its way to show the durability and lifespan of their coilover products, and have done promotional videos touting how much abuse they can and should take. Anything can break at any time. The question now is, since the warranty is probably over, will they work with this guy to replace the shocks at reduced price? Rebuild them? Or is he just SOL?

I agree with you, there probably is more to this scenario than meets the eye... I'm disappointed though that LG hasn't stepped in to say anything or defend themselves, or to even acknowledge the situation. That weirds me out and leads me to wonder what's going on. I was actually gonna pick up a set of LG coils myself, but until this is sorted...

With all due respect, a modded car is a modded car. I think after 5 yrs you gotta just take it on the chin. I doubt for the money involved, you'd install coil overs to make runs to church on sundays. It's never fun to brake parts but it does happens. I'm a mechanic myself, if stuff lasted forever, I'd be out of a job.

one of the reasons i buy parts MADE IN USA from American companies is they will usually work with you in case of an issue such as this. I would have called LG before posting on a forum. Did you buy the parts new?

from what i can see it looks like replacement of the shaft, adjustment rod, and perch would have this damper working again...

Yes... I stand fast... "IF" there were a quality issue with the LG Motorsport shocks it would have reared its ugly head long before now. I said nothing about 1 or 2 months but I would say a "quality" issue is most likely to show up long before 5 years. I would add that you would see the same issue repeatedly with other Vette owners using the same shocks... but you don't. I see no evidence of poor quality or "design" which is what I view to be the actual topic of the promotional video. What I DO see is evidence that these shocks were pressed well beyond their design limits. Kudo's to LG if they help this guy out in some way but I would not expect them to do so.

The shock mounts are designed to take the load created when the car bottoms out on its bumpstops. I would imagine that force is much higher than running a coil spring.

I don't have a dog in this fight but in regards to LG taking care of it, how many items do you own that have a 5yr no questions asked replacement warranty? Why is it car enthusiasts (and this applies to all brands) always expect these manufacturers to replace everything at no cost no matter how long they've had it? Your car from a multi billion dollar company doesn't come with that kind of warranty. Why would you expect a small (relatively) company to offer better than that? No one likes to admit it these days but **** still happens which is exactly what happened here.
