So i was looking at my suspension components to see if I could notice something wrong that could be causing my vibrations on my lowered AWD.

What I did find was a tiny dots of grease that squirted out of the inner CV boot. Its on both sides. My car has 43K. What the heck? I hope this wasn't caused by me lowering this car...

I checked the boots, there were no rips. it appears that the grease came from the end where the clamp is. I hope it just needs a new clamp or something.

I dont think the springs have anything to do with it. I would take it in to the dealership and let them look at it. Its still under warranty. Remember that the dealerships want to do the work and bill Lexus. They are not going to hassle anyone for something like this even if it did cause it.

I had a custom tuned ECU on my G35 and I blew 2 injectors and the tech knew I messed with the motor and ECU and they still had it covered under my warranty. It all comes down to dollars and cents

I hope this doesn't have anything to do with with my recent change from springs to coil overs.

Will the dealer claim "void" once they see my coil overs?

So my list for them thus far:
1. Metallic rattle grinding upon start up
2. CV boot leak
3. Vibrations upon acceleration and deceleration between 10-20 mph

I only have about 7K/3 months left on warranty so I need to get these all checked out.

^ what I8ABMR said..
i'm keeping my eyes on them also, but i don't see any leaks so far. take it to the dealer and see what they say, just like that guy posted on IS suspension sub forum. when i had vibration issue with tein springs, two mechanics i spoke to, one independent shop owner and the other guy in honda dealership, still recommended me to go to the dealership with the benefit of doubt. i didn't go since i was 100% sure that vibration was caused by lowered suspension, but will do if the boot is starting to leak..

Dealer said the boots are fine and so was the clamp. They said that grease will continue to leak out due to the altered suspension.

I guess I'll just have to just monitor the situation - hopefully it doesn't get worse.

They also mentioned that I had the wrong coilovers installed because the sticker labels on the BC coilovers said IS 250 AWD. So for those with BC Coilovers on your GS3, remove the sticker before you take your car in. I explained it - but he was didn't seem to care.

Regarding the vibrations - "nothing we can do" as there is no insulation between the struts and the engine due to the altered suspension. DAMN.

Did you have those problems before installing the coilovers, or is it just dealer's excuse?

I noticed it after I got my coilovers installed. I think the performance shop I took it may have caused it. I'd go back but I think it will be a waste of time because i don't have evidence to back up my claim.
