Bumpy lc200!!

[soh299]

Hi guys, I have a diesel LC200 from europe.

I find it quite bumpy at the front row, and even more bumpier at the 2nd row of the car. It seems like the car is constantly finding holes even on an even road.

Any of you guys experience it? Or am I too self-concious towards it.
Its unbelievable that the ride could be like this, consider the premium price paid for it.

Anything i can do to reduce its bumpiness? for example, adjusting its absorber's rate?

Would appreciate any helpful comment especially those who had experienced this issue before.

Many thanks.

Since you have the diesel, I'd try the LCOOL forums as everyone here primarily has the petrol version.

You do have to remember that the LC is a truck and not a car or crossover. It's built on a boxed frame with a solid rear axle, unlike many other SUVs.

I dont think i would matter much on whether its running on diesel or petrol.

The main point here is, shouldn't this latest LC, which has all these technology and comfort interior drive like one as well? Even my 10 years old Prado doesn't give such a bumpy ride.

And yes, i did tried all modes, comfort, normal and sports. Its all roughly the same.

To be honest, quite disappointed with Toyota's quality nowadays.

I too find my LC200's ride to be kind of stiff (my AT tires aren't helping). So I lowered the tire pressure a little and got Wet Okole seat covers which provide a layer of cushion. And, yes, I reminded myself that this is more an expensive utility truck than a luxury truck.

It absolutely would matter. The diesel engine weighs quite a bit more and has different shocks. There is also an entire thread on a steering wheel vibration that is only applicable to the diesels over on LCOOL. Obviously, something is different if they are having vibration issues and we are not.

Also, you appear to have AHC with adjustable suspension. You probably can raise and lower the suspension too. We cannot. Those shocks are reserved for our Lexus version. It's a drastically different setup. Do you have a solid rear axle (SRA?) I don't even know if you do or not...

As for BigDouggieDoug, he hit the nail on the head. Again, this is a utility truck, not a luxury truck. It's not a Lexus! For the purpose of the vehicle, I WANT to feel the road I'm in contact with and WANT to feel like I am in a built truck and not floating on a couch.

With AT tires, especially if they are LT-E rated, you are GOING to feel everything. Deflating the pressure can help, but be very careful with this as as you add weight, you need to increase the pressure. If you have bumpers, winch, skid plates, sliders, etc. you are going to have to run a higher PSI to compensate.

I run my AT's at 40PSI and love the ride. I hate how deflated tires make the truck squirmy on the highway. I have improved handling, steering, comfort and confidence at the higher PSI. In addition, my fuel economy is better at 40PSI than at 33PSI, even though it's only 12-14mpg now, lol.

Again, I'd recommend talking with others who have the same engine and now apparently suspension, which none of us have.

Not true, we have both engines and driven both. No difference at all... Oh yes to tell you the truth you got more troque and MPG in the diesel version, but for a real truck like you say it's better to avoid a gasoline version, as I remember the most valuable pick up truck are diesel.

More over, with a difference of 100 pounds between the two engines, it's not relevant especially if you intall a bull bar and winch.

But for your market you only stuck with the gas, too bad, I think you'll love having one.

 

[soh299]

Yup, It is true that the diesel has more torque. As for the consumption, mine is around 24-27 MPG.

The main point of this thread is to know whether all the LC200 users are experiencing this bumpy problem or not, and whether there is ways to reduce it.

I can feel that its very smooth to drive and sit on, just that it is bounching too much, even on even road, its finding holes in it. I wonder would it be the absorber bouncing rate that is causing the problem. Hmm.

 

[phatairman]

What kind of tires/wheels are you running? If your running 20 inch wheels and low profile tires you will feel every divot in the road.

I doubt you have that setup since your 200 isn't a NA spec, but it is a thought.

Not true...

Before criticizing, I suggest you re-read everything here.

US spec LC200's do not have AHC (Active Height Control) and AVS (Adaptive Variable Suspension). His does.

Yes, there is a difference


If you care, here is the thread regarding the vibration in the 200 with the 4.5L TT diesel:

Can you please tell us what size rims and tires?

What tire is it?

Also, what PSI are you running them at?

 

[soh299]

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.

Well there's your problem! Ditch the 20" wheels. Put on the factory Toyota 18" wheels with an all season highway tire, preferably the stock size of 285/60R18. You could run a bit larger of a tire, but no reason as you are not offroading (implied by the 20" wheels you currently have).

I'm not sure about the 20" wheels, but with the 18" wheels and highway tires, you should be running 33-35psi.

Those 20" wheels are most definitely the culprit.

 

[soh299]

Yeap, i guess the wheels are behind the reason. I guess we cant have both beauty and comfort in one.

 

[phatairman]

I glad we found the culprit! Now change out those wheels and tire and enjoy your 200.

 

[JBHorne]

Yes you can! 18" wheels look perfect on a 200 Leave the 20's for the Escalade's and 300M's.

17 inch wheels for cracky rides

 

[tempestv8]

I have the 17" wheels on my LC 200 diesel which has KDSS, and the ride is very soft. Almost too soft, with a wallowy feel like most big American cars. I can say that because I have driven a number of large American cars including the Ford Thunderbird coupe. Wallowy. But that's what I like, so the 17" wheels suit me just fine.

Most road imperfections are ironed out and just feel like a mild tremor. Certainly not a harsh ride at all.

 

[soh299]

Actually, i had found out that the ride is not actually bumpy, but is swaying left and right too often even on normal roads. kinda disappointed on a car of this price tag.

If you cannot even figure out if the ride is bumpy or is swaying, then how on earth can anybody here figure out how to help you?

Get somebody else to drive the truck and report back to us with their synopsis, and maybe somebody can help.

 

[soh299]

Thats because the swaying is making me feel bumpy. And when i really feel and think about it, its actually like what others had said. The ride is soft and smooth, but swaying too much.
