Lx470 Front End Bouncing

[ira057]

I purchased a 1999 lexus lx470 and the front end started bouncing. I took it to a lexus dealership and they said someone had put the wrong fluid in hydraulic system. They replaced shocks and purged system. I also purchased brand new tires. They said the sensors checked good but the truck still has a noticeable bounce. Can someone please give me some advice. Will be very appreciated.

they have to do more than replace the shocks if the system was contaminated. If it was OIL , a simple fluid flush will do. If it was antifreeze or brake fluid--a complete system replacement is in order--the antifreeze and brake fluid destroy the 'rubber' components in the accumulators, struts(shock cartridges), electronic solenoid valves,etc.

If the symptom is a very choppy/bouncy ride--check to see how much suspension travel you have. It should be quite a bit. It is's just a bit, then the 'accumulators' are flat/nearly flat. They slowly loose their nitrogen pre-charge and cause the choppy/harsh ride. You can either replace them ($500-600 each+ labor) or have me modify and recharge them.

I suspect you have flat accumulators.

I think it is always a good idea to get the problem looked at by 2 dealers or a dealer and a auto shop and see if their diagnosis match. I don't know about your area but where I live, they just want to do the first fix that comes to mind and if you still have a problem they just charge you some more for another fix.
