Default Help, my suspension is lop-sided

I'm trying to decide on what i should do with my 93 ls400. I noticed that the driverside is a little bit lower than the passenger side. By about an inch. What should i have replaced? I want a smooth ride as top priority. I have noticed my 93 is looser than my 94. There's only a 15k mile difference between the two. I don't know what to do and where to start! thanks for the help.

PS i already searched. Couldn't find what i was looking for.

Also I DON'T have air suspension.

i think its the same issue i had with my honda civic long time ago. It was lower on the driver side and the shop side since it had like 170K miles on it the shocks and spring might be worn out given that I am pretty much the only one in the car putting all the miles in it. The mechanic recommended to swithc the shocks and springs to even out the car but i was a student back then so i chose not to. Its nto going to mess up your performance but will look awkward. So in short, it might be the shocks and springs if you are the only one sitting in the car. Hope that helps.

Actually, thats how most Lexus' are, from LS' to GS's. The driver's side is always lower (i've noticed this on some of my friends cars as well), its just that you never notice it, unless you stare for so long, and everyday... AKA when you buy it.

Usually, there is about .5-.7 inches difference.

Now about the suspension being loose... well, that really depends on where both were driven, the roads, type of driving etc. Best way to get some solidness back is to change out the sway bar bushings (Fairly cheap) upper control arm bushings (Daizans').. that would make a world of differences. Check out lexls.com for pics of the install. outer tie rods.... etc.

I've not owned a car that isn't uneven like this to some degree. Even a few with air suspension where it is bottomed to a bump stop, it's off by 1/8"-3/8".

The problem would be a rusted, sagging, worn out spring. Struts do nothing in regards to the height of a car

you would be incorrect.

Llevo is correct - the shocks (in the strut) just dampen the suspension - they do not carry any weight - that's what the springs are for.

Most likely spring sag from time. My 90 and 91 and my dads 90 are all level, but my brothers 94 was about an inch low on the left side. New springs took care of the problem.

There are some aftermarket suspension setups that give a drop with springs and adjustable shocks that give you an extra drop. But generally the springs do provide the drop.

Curiously, the points you are looking at, what do they measure out to be on a level surface? I'd want to know this before going in so when you do change parts, you know how much correction you achieved.

Depending what baseline for measurment, measure ground to fender well top arch or lower portion of wheel rim to fender well arch. 3/8"-3/4" differences can be normal. The strut mount rubber may also be compressed and likely so at this age.

Largely in this day, metallurgy is good that spring fatigue isn't as common. It varies on car so it doesn't make much sense to test the spring when buying a new one is easier.

So in one swoop, I'd swap springs and the strut mount. Check the other suspension bushings like the upper and lower control arms.
