Hey All,
I've got a 2000 LX470 with the original AHC still going strong (?) at 245k miles. I believe the only thing that has been replaced is the front shocks, due to leaking, by the previous owner (done within the last two years).
Anyway, I will occasionally cycle through the ride height modes, just to work the system. Not sure if I should be doing this or not, but I feel like checking it for functionality every few months isn't a bad thing. That way I can catch any issues before I'm out in the middle of nowhere on a trail.
I've noticed recently that, when I have done this, it can take a really long time for the height to adjust. When I attempted to go into 'Hi' mode yesterday while parked, the light just kept blinking without anything happening (maybe for 20-30 seconds). I put it in drive and then reverse, and eventually it did go into Hi. Same thing when I went from normal to low.
It just seems like it takes a little coaxing and patience to get the AHC to respond these days.
My question is .... is this pretty normal for AHC to do? Or, is it a symptom of impending failure of one or more of the components? Is there something I should be checking or doing?
I've checked the 'gradients' between hi and low, and it seems to be within reasonable spec. Both of the Land Cruiser shops I've taken it to for other work (including TorFab), have been pretty adamant that they don't / won't service the AHC system and that they believe it is better to leave it all alone....which seems odd to me, but I don't know.
Thank in advance for any answers / observations / feedback on this!
Cheers,
Jeff
