Seized UCA Bolt
So I replaced all four tie rods on my 1998 Ranger XLT RWD (apparently you aren't supposed to hold the shaft and be able to shake the ball joints like jingle bells), and I brought it into Midas for an alignment. The tech told me that they adjusted all of the angles except the L caster angle which he described as being "a little off" which may cause "a little pulling to the left". Let's just say it is more than a little off and the truck pulls hard to the left. The tech stated that the issue was a frozen upper control arm bolt and this is where my question comes in:
What needs to be done in order to un-stick this bolt and be able to adjust the caster angle? Is this just a matter of getting the nut to come off, or is the bolt likely seized inside the bushing? If it is seized inside the bushing, what are the odds of being able to work the bolt out and replacing it without having to replace the bushing? I replaced the leaf spring shackles a year or so ago, and those bolts fused with the rubber of the bushings so they were a bitch and a half, possibly two bitches, to get out (ended up having to cut the head off, and using a ball joint press to force the whole bolt/rubber mess out). Am I looking at the same thing here, or will the bolt come out cleanly (once I get it un-stuck and free of 16 years of rust)?
Any advice or suggestions would be greatly appreciated! I just want to know what I am getting myself into before I start...
