1990 Lexus LS 400 Questions & Answers
1990 Lexus LS 400 Right Front Suspention Thud Noise
most probably a torn lower suspension arm rubber bush that would not show up if the car was on a 4 post hoist
there is a problem there as the noise would not be evident if there was nothing wrong
different tire pressures will give different noise when hit with a tire lever ( a trick used by truck drivers to check for flat/ under inflated tires
good tire solid sound
low pressure tire a dull sound
Where is the fuse for the tilt steering wheel
It seems no one knows the answer. It may be a circuit breaker instead of a fuse. Or maybe a fuseable link.
I found several YouTube videos on replacing the motor, or replacing a plastic gear that's part of the system. If you watch them, it may point you to an answer.
Que puedo hacer con mi lexus ls 400 de 1990 el velocimetro no indica la velocidad en que corre mi carro
Hi Jorge. Por ahora, s?lo conduce a la misma velocidad que todos los otros conductores.

Why won't my car not turn over when I am trying to crank it?
check for spark from the spark plug wire pull the plug wire put a screw driver in the wire hold it by the plastic handel so the shaft of the screw driver is close but not touching a ground and watch for a spark be careful not to get shocked or see if the fuel pump is bad sometimes you can hit the gas tank with your hand while you turn the engine over you have to hit hard and fast while trying to start it this means the fuel pump is bad if it starts because it will stop again
How to check timing
Best bet is the it to a toyota dealershipnor Napa and have them hook up the computer. They will tell you if your timing is off.
