Hi all, I believe I have posted here before a long time ago with my old LS430 LEX, I now have a 2007 LS460L with 110K on it now. I have owned it for a few years now, since 65K miles, and recently I started having acceleration/hesitation problems. I did alot of research, and didn't find very many good answers. I did have the transmission and engine ECU update flashed, with some improvement, but after that didn't solve the problem, I was convinced it was the cylinder head replacement deal, which was way out of my budget with 5 kids....and I thought it was ridiculous that a flagship sedan would need that kind of serious motor work with just 100K on it. Anyway, my mechanic suggested BG 44K fuel system cleaner, NOT available at places like autozone. He sells it for $28 per can, but I found on Ebay for $16.75 and up with free ship. First and foremost, I ALWAYS used quality, premium gas (Shell V-Power or QT), and Techron additive from time to time, so I was super unconvinced about his recommendation. I had even listed my LS for sale, again, convinced that the motor had cylinder issues after reading blogs about LS460 acceleration issues. Also, for the record, I have NO affiliation with BG or anything like that. THIS STUFF WORKS! It truly fixed my hesitation problems, completely. I am no longer selling the car, and am happy again, as it accelerates like it is supposed to. Feel free to read many other peoples reviews on this stuff, its amazing and really seems to work. After i drove it to wrok (25 miles one way) I thought i felt a difference, by the drive home, I KNEW I felt the difference, after the full tank, i was truly smiling. I have ordered 4 more cans for my other vehicles and boat, and suggested it to my friend with a ISF, my brother with an SC430, and my buddy with a Vette. I guess these LS460 cars are just picky after a while and maybe the injectors get gummed up? I don't pretend to be a mechanic, again this was suggested by my Lexus mechanic, After alot of depressing research with no real answer, just wanted to share my experience with any other LS460 owners, as it is a beautiful car, and I was disappointed in what I was thinking the problems I had. It was the best $17 I have recently spent, and if you are having similar weak/lack of acceleration or hesitation issues, i would say TRY IT for less than $20. I believe you can go to BG's site and find a local dealer, again, not autozone or O'Reilly or anything like that, says professional use only lol. Also, need a funnel, comes in a coke can basically. Just my 2 cents, hoping to help out any other LS460 owners out there depressed about their car, it seems most people just said they'd trade it in and buy a new one, but I'm not that rich :)

My 2000 LX470 with about 160,000 miles lost it's suspension fluid, via leaks through the shocks, accumulator, and rusty lines. LEXUS wanted about $8700 to fully repair....and that did not include a new pump or other leveling switches which were working. I did some research and I just converted to a Toyota 100 land Cruiser type suspension system for about $1,700 installed. The ride is great, but I lost the rise and lower feature of course. There are a few kits on the market, but I choose Strut Master mainly because my mechanic had good luck with them in the past. My kit was $500, and labor to install was $1200, which included a new alignment. The top of the rear shocks are a !Removed! to get off, so my mechanic cut a small hole in the floor above, and patched it after the install, which is hidden under the mats anyway. The kit has 4 shocks and two stronger rear coil springs to simulate the Landcruiser. I highly recommend this conversion as once the hydraulic suspension begins to go, you could spend thousands to repair. The original system has so many parts that can fail so I highly recommend the conversion. My 17 year old LX470 is probally only worth $8,000 now, so I am not concerned about any loss in value from the conversion. And I never have to worry about expensive repairs on the suspension ever again.

Regarding the leaked grease from the CV boot, I discovered the same issue about 7+ years ago. There was no clamp there so I got a CV boot clamp and a tool to install one. SInce then I haven't noticed any problem. In addition to this boot issue, my RX suffered the same years ago and that eventually lead to failure(making sound when turning the wheel) so I got it replaced. So I wouldn't be surprise if that could be the culprit. Another thing, if your tires are worn pretty low, you may feel the shake more so than a newer tire. Its been my experience that after I replaced my tires(about 4 sets since I owned my GX), the shake goes away or not as apparent.

The GXs usually have a bad vibration issue due to high road force in the wheels. Especially after you've gotten a wheel rotation and then start noticing the virbration. But Yes, by simply balancing the wheels and correcting the road force, it will take the vibration away. Start with the cheaper fix before you get into repairing the cv boots or performing any type of suspension work.
