Navigator Nose Dive!
Hi All
I've been lurking around here for quite some time but haven't been able to find a solution by searching, so it time to ask for help. My 98 Navigator is constantly dropping in the front. When I start the car it raises up about an inch or two (like it should???) but when I'm driving slow or even idling the pump will come on about every minute or two for at least 15 seconds. If I'm on the highway at a constant speed for at least 30 mins I get the Check Susp light, but never in the city. I've checked the front shocks (replaced one), lines going to them, the lls union and the compressor (well what I could see without removing the washer fluid reservoir) but can’t see any leaks. The rear seems fine as I'm not getting the "sag" in the back that everyone mentions, But when the check susp comes on the front is a lot lower than the back, Is there something I'm missing?<O

Thanks in advance, <O></O>

Ck Susp comes on when the compressor has run too long to acheive desired ride height. This could be due to a leak or could be due to the sensors commanding additional lifit inappropriately and this may be a failure of the component, maladjustment, or both.

Thanks guys, I haven't been able to see any leaks so far. I'm assuming i have to remove the washer fluid resevoir to get full view of the compressor so I will try that this weekend. I just got the truck about a month and a half ago so not sure if ride height was ever "set". While sitting in the car I can actually see the truck rising and falling. If there was a leak wouldn't the whole truck drop or back sag and not just the front?
FTE Herman, are these sensors something that I can check myself?
