I purchased a 1999 wrangler Sport, with 100k miles on the clock, 2 weeks ago. So, far, I've just been tuning her up(Fluids, plugs, wires, cap and rotor). The Jeep has 31's on right now and rubs a bit on the lower suspension arms at full lock, but seems to clear them fine otherwise. Granted, it hasn't been offroad yet and I have no idea what my clearance will be like when the suspension is stretched a bit. So, How can I confirm if the Jeep has already had a body and or suspension lift?
On another note, after changing the oil to Mobil 1 synthetic(10w-30) I've noticed a rattling sound coming from the engine bay. It's mostly obvious at idle, but I think this is due to fan/engine noise at higher RPM's. Any ideas what it might be?
