Found a relatively low mileage (130K) '04 Exp NXB to replace my '00 Nav (229K) as a tow vehicle for my utility trailer and RV. Does seem to have a slow coolant leak (I'm guessing the intake manifold or gasket) that I'll have to deal with.. Few questions--
1. Should I get air assist shocks to allow adjustment when towing? If so, recommendations?
2. I usually go thru all fluids but I'm confused about limited slip differential--Oil weight spec seems to have changed. There used to be special limited slip oils now it looks like you use an additive? If I test and find the limited slip is shot, I'm tempted to not worry about it.
3. Any other general recommendations, must check items, or mods given my intended use for this year/model?
Thanks!
Eric
