Bumpy lc200!!

[Atticus]

Go buy stiffer shocks.

First of all, thanks for all the replies.

Mine is running on the 20" wheel. I'm don't have much knowledge about tyres, but I guess mine can be considered as a low profile one. Dunlop, 265 if I remember correctly.

I'm not sure about the psi as the driver takes care of all these. What psi is most recommended for my type of wheels. An if because of the bigger rims I'm running which causes the bumpiness, I might consider changing it to smaller size one.

Maybe next time you could have your driver post instead of you. That way, we'd have somebody asking questions who can tell the difference between bumpy and not bumpy.

slumpy...maybe?...lol...but to answer the question of a harsh ride over inflated low profile tires on a twenty inch rim will give a hard ride but good cornering characteristics at high speeds...

Are you soh299's driver?

I could be...

 

[shenil]

since you've got AHC....set the shocks to soft...as for the correct tyre PSI ask the tyre technicians at your dealer. lowering the pressure will give unwanted wallowing and handling.

cheers

will anti-roll bar help lessen the swaying problem?

Pictures of your 200-series to show you're a bonafide owner would help and make people more inclined to answer your questions. Check the KDSS valves haven't been left open is a suggestion, but your posts aren't really adding up.

The problem you are describing sounds like you need to correct your caster. I am assuming you have a lift on your LC200 already, and if that's the case I bet your caster is at the bottom end of the spectrum which would cause your truck to wander around the road. By adding aftermarket upper control arms that will correct you caster back to factory specs and you will no longer have the wandering affect that you are experiencing. You can check out the Total Chaos upper control arms here for more information https://www.metaltech4x4.com/p-76-08-landruiser-uca.aspx

Absolutely check your KDSS valve!

Like others have said, you're posts aren't adding up. You fail to even diagnose the difference between "bumpy" and "sway". They are nowhere near the same thing. You should be able to identify if the bumpiness is actually a cadence, in which case it could be out of balance wheels. If it's uneven bumpiness, there are completely different ideas as to the cause. Sway is something different all together.

Hey guys, thanks for all the advise.

I know my post is'nt adding up and i haven proof of owning a LC200 -___-' , but would someone be that free to post in a 4x4 forum, specifically a Toyota LC200, about its bumpiness?

Anyway, after trying very hard to identify the problem, i find the main problem to be ' swaying '. Setting my suspension to COMFORT makes it worst while changing it to SPORTS makes it better, but still.

p/s: i had never done any modification or lift to it.
p/ss: how do i check my KDSS valve. DO i need to send it to mechanics to get it done?

i don't think KDSS and AHC are both available together, so that is not going to be your problem.

ask your mechanic to test drive and determine if the behavior is abnormal.
