I was over at Expedition Portal and noticed that on their Toyota expedition vehicle section there were only three 89-94 model Toyotas posted in 91 pages of posted vehicles. Is there something wrong with these model years that I'm unaware of that makes people not want them? Where I live I see them all the time.

Second question: I have a rattling sound coming from the front end of the truck, a 94 ex-cab 4x4 w/22re. The sound happens when I hit bumps in the road or go over speed bumps. When I bought the truck my mechanic said that the idler arm on the front suspension needed to be replaced. I'm not asking for a compete diagnostic analysis here, but wondering if the idler arm could cause things to sound loose?

Third question: The back end of my truck sags. I'm pretty sure the former owner didn't haul stuff with it. He barely used the truck. My roommate, a mechanic, said the springs are shot. I figure if I'm going to replace them I want to replace them with an upgraded version. I'm just looking to get the truck back to stock height, but for it to have enough strength for me to build a storage system in the bed and not have the truck sagging again. So, are there any good leaf springs that folks can recommend? Should I go aftermarket or replace with Toyota/TRD?

One last question: Are the heater controls supposed to light up? This is my second Toyota truck and neither have/had a lighted heater control panel. My friend swears that her friends 4-runner heater control panel does indeed light up. Do I just have a burnt out bulb? If so, how do I replace it?

Thanks everyone.
