Discovered another bastardization of my "new" LS430.

Every time I stop or start, I feel movement and a shift in the driver's seat so I thought I would try and figure out what is going on. I was hoping something was loose and the fix would be easy. It appears otherwise.

I removed the bolts securing the seat to the floor and tilted it back to look underneath. It seems someone has done a repair to a support inside...I see some low quality welding.

Anyway, does anyone have a tutorial on taking the seat apart? Basically I need to remove the lower undercarriage of the seat and figure out how to properly repair it.

 

You can see the weld under the bolt head. I can't tighten the bolt any further and there is movement.

 

If I can get these last few details fixed, I'll have myself a nice car! Hard to believe it is 10 years old.

 

Here are pages from the LS430 repair manual. Hope you find your answer in there!

 

Excellent! That will lead the way perfectly.
