What are time and material costs to change a king pin on an Isuzu npr?

Answer 1

Here's a quick break down of parts and labor for replacement of left and right king pins on an Isuzu NPR.

Removal of tires, calipers, hub and rotors, ABS sensors, backing plates, drag link, tie rods from spindle, king pin set pins, king pin grease caps, hammering out old king pins from axle/spindle, press out old KP bushings, press in new KP bushings, size bushings to new KP using hone (as needed), set up of end play of spindle using new shims and lower bearing, repack all 4 wheel bearings with new grease, new grease seals, new kp set pins, new kp grease caps, grease new KP, and finally, reassemble of previously removed components. All this at a decent truck shop will run you about 8 hr's of labor.

Road test and check for drift right to left, pulling right to left, steering wheel clear vision centered. If any faults are found either caster/camber will need to be addressed. To correct pulling we use 1-4 degree axle shims installed under the front leaf spring(s) to correct a pulling condition. If vehicle drives good and straight then toe adjustment is recommended for good measure. Also removal and centering of steering wheel as well. This repair and adjustment for caster/camber/toe set and center steering wheel is 2.5 hr's of labor. If only toe and steering wheel centering then it's 1.2 hr's labor.

Parts for this repair are around this:

King pin set: $350.00

Front grease seals: $20.00

Brake clean: $6.00 each

Grease: $ 5.00

Axle shims $ 15.00 each

missolanias freight tax etc: $150.00

Scenario 1Labor @ 120.00 an Hour @ 10.5 Hr's=$1,260.00 (caster camber/toe-set)

Scenario2" " @ 9.2 Hr's=$1,104.00 (toe-set only)

Parts approx = $550.00

Parts and labor scenario #1= $1,810.00

Parts and labor scenario #2= $1,654.00

This is what my shop has charged for king pin repairs with the above noted procedures done. This is an approxamete give or take a couple hundred but prob pretty close to a decent truck shop will charge for an Isuzu NPR king pin replacement. Hope this helps.
