2. Check the wheel bolts and wheel nuts
for the following:
• Cracks or other damage
• Check to see if the bolt is elongated.
The standard for the bolt diameter
is 22 mm (0.87 in). If the actual
diameter of the bolt is 21.5 mm
(0.85 in) or less, replace the bolt.
Also, check to see if there is any
noticeable rust.
• Crushed, thinned or seized threads
Replacement of the wheel bolts involves
disassembly work, so ask the nearest Isuzu
Dealer to do this.
• Check to see if the washer rotates
smoothly. If it doesn't, replace it.
3. Remove rust, dust and mud from the
fitting surface, hub fitting surface or
wheel-to-wheel mating surfaces, and
wheel nut seating surfaces (tapered
surfaces) of the disc wheel, and from
the threads of the wheel bolts and
nuts.
If there is rust on the hub and the
stepped section of the disc wheel
(unpainted), remove the rust and
apply a light coat of grease.

4. Lubricate the threads of the wheel
nut.
• Apply lubricant via the clearance
between the nut and the washer.
(This is not necessary for a new nut
and washer.)
• Lubricate the threads of the nut.
