The shop costs are all labor. $98X3. They do book hours & book says 1.5 hours per side.
Having done this upside down in my driveway without the special tools I think I can say that 1.5 hours per side is significantly over the top for a shop with a lift, air tools, and the correct tie rod tool.
This is the procedure (more or less as it would be done in a shop)
0. PB spray the castle nuts and lock nuts on the outer tie rod ends (they may not do this in a shop)
1. Break free the lug nuts on both front tires and put the truck on the lift.
2. Remove a front tire and remove some of the composite inner fender guard (may not be necessary)
3. Us a box wrench to break free the locking nut on the outer tie rod end and then snug it back up
4. Remove the cotter pin and castle nut from the outer tie rod end and pop it out of the knuckle
5. Us a box wrench to break free the outer tie rod end and then snug it back up
6. Remove the outer tie rod end counting the number of turns, record the number
7. Remove the lock nut
8. Remove the small outer spring clip on the rack boot
9. Use a large flat-head to pop the inner band clamp off of the boot.
10. Remove the boot being careful when disconnecting the breather tube
11. Attach the correct crows foot to the hex on the inner tie rod end
12. Attach the tie rod end removal tool to the crows foot and break the tie rod end free
13. Unscrew the inner tie rod end
14. Turn the wheel to fully extend the exposed end of the rack gear and inspect it for corrosion
Installation is just that list in reverse. Replacing the inner band clamp with a worm gear clamp is a pain under the truck in the driveway but up on a lift with a band clamp tool it should take a matter of seconds. You also have to jack the lower control arm back up to ride height before re-torquing the castle nut on the outer tie rod end. I suppose in a shop they may just put the truck back on the ground to do this.
I don't know, does that really sound like 1.5 hours per side for a mechanic in a shop who has done it many times and has all the right tools?
With the correct tool I think I could do it in the driveway in 30-45 minutes per side if the nuts were sprayed in advance. Even replacing the inner tie rod ends, outer tie rod ends, and rack boots with top quality Moog parts (~$75-$85 total with shipping) I would still expect this to come in at around $200 to $250. I think that just the inner tie rod ends for $400 is excessive to say the least.
Are you still going to do the repair today?
