Toyota AYGO

Sticking Wheel Prevention.    
 

Several people on the Toyota Aygo Forum have experienced
difficulty in removing alloy wheels from their cars when
they had a puncture.

This is caused mainly by corrosion due to salt, moisture and
having bare aluminium (The Wheel) and bare steel (The Hub) in direct contact.

Now summer is here, take a few hours to sort the problem out
and prevent any future problem.

I hope this isn't patronising but some people aren't mechanically minded so......

First: Off to the shops (Halfords etc. or ebay) and buy some Copper Grease.
This may be branded Coppaslip, Coppagrease or similar......



Secure the car for jacking one front corner.
Handbrake applied firmly.
AYGO in gear. (If you have MMT, ignition on, foot on brake,
lever into "R", ignition off).
Chock behind diagonaly opposite wheel.
Slacken all four wheel bolts about three turns.
The weight of the car should now dislodge the wheel slightly.
Jack up the AYGO until the wheel is JUST clear of the floor.
Remove the wheel bolts fully and take off the wheel.

At this stage, get mucky......
Clean the rear of the wheel. I use a kitchen sponge and
liquid Flash or any similar multisurface cleaner.
Wash it all off and allow to dry.
Polish the rear of the wheel with normal car polish / wax etc......
dab the Copper Grease on the mating surface of the wheel.
(The brown bit).



Dab some onto the mating surface of the hub too.
Especially the central locating flange. (Yellow Arrow).



Apply Copper Grease to the wheel bolts.
ONLY on the threads. NOT on the tapered or conical part.



Replace the wheel and hand tighten the bolts.
Lower the AYGO to the floor and fully tighten the bolts
in a diagonal manner.
Torque setting is 103Nm (+-15Nm) 76lbf (+-10lbf)

Cup of tea, the the other front wheel......

Cup of tea, the rear pair......

On the rears, the wheel backs should be much cleaner.
Only Copper Grease the area of the drum brakes shown......



Again, paying attention to the raised flange. (Yellow Arrow).

Wheels all back on......admire your handywork......
Round the AYGO one last time to check tightness of all bolts.

Job done:
Next time, with a rainy winter roadside puncture......

Wheel straight off !
