Not a silly question. Just through the city. It wouldn't have had a chance to get a lot of pressure from heat if that's what you're thinking. 30 minutes tops.
I'll see if I can snap some pictures sometime today. I'm at work so it might be tough to get out and under it.
My main concern is the rate at which it's leaking. It doesn't look like it's dripping oil but I'd hate to have it run dry while I'm on the road before I've had a chance to fix it.
Just had my 99 runner serviced for the first time in 2 years (I live in Vancouver so it sits 90% of time).
I went to a lube place who told me my rear diff was empty?! I know they are up sell artists but that got me concerned. I had them fill it and asked if it was leaking. They said no...
