Winter tyres

mikey72

Just got the winter tyres out, and put them on the car.
(Why do modern cars have nowhere to put a trolley jack under anymore?)
Back two came off reasonably easy, and I've got the chinese m&s back on again. (note to self, new pads - metal on metal isn't good)

The usual front wheel had welded itself onto the hub, so on a combination of the car jack and the trolley jack, and belting the rim with a lumphammer and a piece of wood eventually pursuaded it to move.
The other side came off by itself though.

The only bit that gave me cause for concern was the loud clonking the wheel I belted repeatedly made when I pulled the wheel in/out top to bottom afterwards.
Driveshaft/top suspension mount/balljoint?
No sign of anything visibly moving, so I drove it up and down a few hundred yards and whatever I disturbed went back. Driveshaft I think. Maybe.

Don't think I fancy being a tyrefitter.

But that's it until March, when I go through it all again.

Maybe the disc was moving with the wheel and then banging back against the hub.

When putting your alloys back on put some copper grease on the hub face (not in the threaded holes or on the wheel bolts). It'll help avoid them 'welding' together again. It's caused by dis-similar metals (ie. steel hub, alloy wheel) corroding and making it tricky to dislodge them). A little grease goes a long way.

The bolts work by causing friction between hub and wheel faces, by putting grease on to these faces you are putting a huge shearing force on the bolts (although to be honest the bolts will probably still strong enough to take it).

Also, as mentioned above, dont put grease on the bolts as they are designed to be installed dry and greasing them will increase the strain put on the bolts when torqued to the correct value (and you may strip threads).

Of course, always check your manual, things might be different for your particular car.
