Hi
The cost involved should be anywhere from 2500 to 5K. It really depends on a number of factors.
First and foremost -- new or junkyard parts? That is a big difference between the 1200 job at home, and the 5 K job professionally.
There's more to it than a simple cut and turn to do it correctly. This is a very controversial subject.
There's a guy here in Sonoma, Gary "Mudrak" Kardum that has done numerous SOA's. (
www.mudrak.com) When Gary did mine, we also did the following:
Cut and turn
Rebuild front axle (gaskets, bearings, etc).
Hy Steer arms
1 ton Tie rods and ends
Saginaw Power Steering
OME 2 1/2 springs (new bushings, Ubolts, etc)
Frame re-enforcements (plates for the steering box, and plates for pseenger side frame)
We also did the Sm420 conversion, so there were new driveshafts as well.
Oh, and you need to factor in the cost of tires.
To me, if you go SOA, you need to have power steering as well.
Here's some of Gary's customer comments. You may recognize a few of the names:
