rough 2010 wagon

[andrew 75]

Any suggestions for a 2010 patrol wagon that is very rough to travel in on our gravel road. Admittedly the road is in terrible condition but the vehicle seems unusually rough. We have put old man emu suspension without the lift kit on the vehicle. Any other suggestions to improve the ride.

Hello Andrew and welcome to the forum,
jump in anytime and enjoy,
Maybe check your tyre pressures 35-38 Psi around town

Gday Andrew welcome aboard mate
Jump over to the intros and say gday, something we ask all members to do, cheers

Thanks for that threedogs. I have tried that and no difference

You may need a softer spring rate, they say Koni shocks work wonders.
Were your shocks bled before they were installed, you should be able to push down on the corner of
the bulbar and see it spring back once.

Hi Andrew and welcome to the forum.

What tire pressure are you running when driving on the gravel road? I take it there are lots of corrugations, ruts, pot holes etc....

I don't know what your experience level is so please forgive me if you've heard this before....

If you are driving on sealed or non-sealed roads that are in good, firm and smooth condition, you can have your tires inflated to the recommended pressures. (usually around 33-38psi. If in doubt, look on the sidewall of your tire and you will see the manufacturers Max tire pressure. I usually go 5-10psi below, allowing for the pressure to expand when heating up. All manufacturers are different. I had a set of light truck LT tires on one patrol that the max pressure was 80psi. I never inflated them past 60psi and never had any issues.)

If you are travelling on gravel roads, with loose or rough surfaces, I would recommend that you drop the pressure to arout 22psi. The thing to remember when dropping tire pressures is that it is the pressure that keeps the tire firmly on the rim. If you lower the pressure then you must be aware of either turning sharply or braking suddenly as both situations will be effected.

If you have lowered your tire pressures, and the ride is still rough, it may be that either your coils are in need of replacing, your shocks need replacing or both. I see that you have put shocks on but were they new? Are they standard height or for a lifted vehicle as this can also effect the ride. (thinking castor correction)

Hope this helps.

Hard to know what you mean by too rough, but it sounds like the spring rate is too hard, or the shocks valved incorrectly.

I would suggest that you try adjustable shocks that you can adjust to suit.

Tyres pressures make a huge difference too, as I use 25 PSI in the bush and 40 on the road, and it makes a huge difference if I dont drop the pressure in the rough stuff.

I haven't had mine long and thought it seemed a bit harsh on dirt roads. I played with tyre pressures and made a huge difference . I still have standard suspension and doin a lot of research before I get new springs and shocks

Thanks for that Wang
