You need to loosen the torsion bar adjusting bolts until all the tension is removed, remember to mark a reference point from bar to frame so you can get close to the correct riding height after reassembly. Can't tell if you split the ball joint from the knuckle from your explanation but a couple of good solid whacks to the lower knuckle will unlock it. Mark & remove the control arm bushing bolts and use a pry bar to push out arm @ bushings.

same as all cars. (mostly)
this your first starter?

Usually accessable after removing starter motor

Its located behind the air intake, by the firewall. It looks like a doughnut with rubber on it, and a wire coming out of the side. Its held down by a bolt. Its just in a hard place to get to. If you remove the bolt first, its easier to pull up by the wire. disconnect the wire, and throw away, connect the new one, and bolt the new one in. ONLY use 20lbs. torque to tighten it down. It will break if not careful(found out the hard way). Its about a 10 minute job

Hi. here's the procdeure on how to remove and replace new starte for your truck.

1. Step 1 Disconnect the battery's negative cable from the battery using the battery wrench.
   
2. Step 2 Lift the right front end of the Ranger with the floor jack and then lower it onto the jack stand. Make sure the jack stand is under the right front frame, but does not impede your access to the starter.
   
3. Step 3 Climb under the Ranger with the socket set and unbolt the starter wiring using the socket set.
   
4. Step 4 Support the body of the starter with one hand while you remove the two starter-mounting bolts with the socket set using your other hand. Do not let the starter rest on the loose bolts at any time during this process.
   
5. Step 5 Set the old starter off to the side and hold the replacement starter in position. Thread the mounting bolts back in by hand and then tighten them down with the socket set. Once again, do not let the starter's weight rest on the bolts until you tighten them down fully.
   
6. Step 6 Bolt the starter wiring to the new starter using the socket set.
   
7. Step 7 Climb out and lower the Ranger off the jack stand using the floor jack. Reconnect the negative battery cable with the battery wrench.
   

frames certainly can be straightened, but must be evaluated on a case my case basis at a frame straightening / body shop.

Use and extension, good luck, nissan starters are a pain!

filter is on r/h side of the frame about half way down the frame. its kinda hidden behind metal plate. you need to remove the plate first to gain access to the filter.

98 frontier what?? V6 or 4 cylinder?? and how much R 134a did you put in there??
