AXLE INSPECTION & REPAIRS
As a general rule, repairs and mainte nance should be
performed by qualified servicing personnel. Our axle
manufacturer recommends that a certified mechanic
should be consulted on the following items:
1. Broken axle
2. Broken spring
3. Worn spring eye bushing parts
4. Sagging springs
5. Welding fatigue
6. Serious leakage of seal
7. Tire wear
8. Loose or worn suspension parts
9. All brake related adjustments, inspections and
problems
Removing the Vortex Hub for inspection or
maintenance should be done in a safe location
away from moving vehicles.
A. Removal of Hub
The following instructions pertain only to trailers
manufactured by Scarab. To remove the hub to in-
spect the bearings and seals, refer to Figure F20 and
the following instructions:
Figure F20: Axle Components
1. Elevate the trailer on level ground using the
manufacturer's instructions. Always use jack
stands or other solid supports. Do not rely on a
jack to support the trailer. Block wheels to keep
the trailer from rolling.

2. Remove the tire/wheel assembly.
3. Place a newspaper or cloth on the ground under
the hub to keep any parts from falling onto a dirty
surface.
4. Remove the Vortex grease cap by unscrewing in
a counter clockwise rotation.
5. Remove the cotter pin, castle nut (in a counter-
clockwise rotation) and washer.
6. Remove the hub from the spindle. If you have

B. Bearing/Seal Inspection and Replace ment
When inspecting bearings or seals:
1. Inspect the grease seal for damage, tears, or
cracks. If there is no damage or leakage is not
occurring, the seal is in good condition.
If the seal is torn or cracked, then it should be re-
placed. The seal can be pried out of the hub with
a screw driver. Be sure to replace the seal using
the recommended replacement parts. Parts can
be obtained from your Scarab dealer.
2. When inspecting the bearing, check for corro sion
and wear. If any rust or wear exists on the bear-
ing, then remove and replace with the manufac-
turer's recommended part.
3. If the bearings are in good condition, repack ing
the grease should be done at this time. Hand
pack each bearing individually using a premium
water-resistant wheel bearing grease.
NOTICE
To maintain the factory warranty, Lucas Oil
Marine grease must be used when adding or
replacing grease in the vortex hub.
C. Hub Reinstallation
1. To re-install, coat bearings with Lucas Oil Marine
Grease before re-installing.
