Whats up guys, I'm the proud new owner of a 87 Dodge Raider, 2.6 4 cyl 5 speed. I bought the car from a family friend and it was not very well taken car of Mechanically, although the interior is very nice! So In attempt to start somewhat of a maintenance schedule for my new wheels I did a tune up (NGK Plugs, wires, cap, and rotor) All the belts, Changed the Engine oil, and Gear oil out of the Transmission, and I want to change the oil out the diffs but forgot to check if my rear diff was Limited-slip. The Truck drives great, the only problem i have is after long drives the engine diesels (Keeps running after shutting key off) So any light on that would be greatly appreciated. Another question is I was reading into cranking up the torsion bars and Toyota shackles for a two inch lift, I understand that pre-loading the torsion bars will cause the upper control arms to contact the bump stops and cause the need to trim them and also affect the alignment. My question about the alignment is By cranking the torsion bar what of the alignment is affected? Caster, Camber, or Toe? is it something a general alignment shop could handle or does it have to be a frame alignment? Thanks for any help, and sorry that I am a noob
