Dummy Drive Shaft | Temporary Wheel Bearing Support
During long term front end work on front wheel drive vehicles, it is sometimes
necessary to remove the vehicles drive shafts.
Due to the lead times involved with certain sub contracted overhaul procedures,
the vehicle may be required to be 'moth balled' for a time with the job half done.
If the vehicle has had its drive shafts removed and must be moved to a suitable
place for storage, it should not be placed back on its wheels with the drive shaft left
out as the weight of the vehicle could force the wheel bearing races to separate so
damaging the bearings.
This means that the vehicle must be left either on stands or a ramp, rendering the
ramp useless until the job is completed.
It is for this reason that a set of 'dummy drive shafts' or wheel bearing supports has
been designed to insert in place of the driveshaft.
Once the tool is inserted the vehicle can be placed back on its wheels and rolled
free of the ramp to free up space in the garage.
This kit is designed to allow the vehicle to be pushed to a place of storage. The kit
must not be used to allow the vehicle to be towed on the public hi-way.
Always ensure the components do not touch or press against any ABS sensors.
Each support is made up of a 5 piece set which includes two bevelled bushes
for either side of the wheel bearing (bearing and hub), a centre lead screw & two
matching support nuts.
This kit has been developed to suit as many wheel bearing variants as possible.
Please consult attached bush dimensions to determine suitability for intended use.
THESE TOOLS ARE SUPPLIED IN PAIRS TO SUPPORT BOTH BEARINGS!

Instructions
Before itting the dummy drive shafts irst check that component (A) its
into the outer drive lange hole and that component (B) contacts the inner
bearing component of the inside of the bearing.
Insert component (C) into component (A) as shown above and insert them
into front drive lange.
Fit component (B) onto the inner end of component (C) and it 2 of
component (D).
Tighten the lock nuts to no more than 30Nm (enough to hold the bearings
in place).
