Lexus Repair: 94 LS 400 rear suspension problem, ngk plugs, 13yo

Question
Hi Brandon, I have just aquired a 94 ls400 with its rear end dragging on the ground. The trunk switch is on and the pump runs the front just fine. Any Idea's on where to start. I am a Transmission Specialist, But have no experience or info on this car. Thank You!  John

Answer
Do you mean that damned AVS adjustable suspension?
Rip that crap out. It's stupid to continue to use it.

Just use normal suspension replacement parts isntead of the AVS. convert it to "normal" LoL! I'm not kidding...
I'd ditch the springs & mounts also. No way they're going to be in good condition on a 12-13yo car.




Otherwise it'll last forever if you really stick on basic maintenance. Flush the transmission fluid, coolant & replace those parts. Maybe flush out the oil sump right before you change it with some seafoam, or something. Get any burned oil out of it.
Denso, or NGK plugs / ignition parts ONLY.
