hi just joined the forum ,just got an ls 400 with 147,000 miles drives like a dream but if left for a while and you start driving the front left hand (uk)shock or arm makes a noise over bumps.but after the engine is warm it stops any ideas anyone?.Also this car is a 1992 do they have remote keylock s

 

go search. theres HUNDREDS of threads on the front end noise.

 

like puredrifter said, there are many threads on this topic or similar topics. I had some knocking noise from the front side before after changing my shocks/springs but it turned out that it just needed to be tightened. good luck
