Hi, i cant take off my rim for the spare. I took out all 5 rim screws but the rim refuses to gently slide out.

I know there is a rim lock somewhere, but cant find it, tried everything

I'm guessing it is fused to the car? Just lower the car with the bolts off until the wheel has good contact with the ground while still keeping that wheel on the jack.

Then get in the car and move the steering wheel back and forth a few times. This is definitely not the first time that a wheel has fused to the axle!

That's if it's a front. If it's a rear wheel, you might have to loosen the wheel bolts (lug nuts ) -but leave them most of the way in, remove the jack, and rock it back & forth using the gears & the brakes.

What Woolly said - drive in a close circle with the lugs loose for the fronts, gently shift into and out of gear while using the brake for the rears.

I guess we are only talking about loosening the bolts by 1 or 2 turns? Just enough to give 1 or 2 mm gap?

The corrosion will take the full wheel load, that cause the seized parts to split open, the load will transfer to the bolts and you'll have a slightly wobbly wheel.

Loosen the bolts too much you could have some big problems.

Hmmmm...........I am not a big fan of driving around with the lug nuts loose. How about using a couple of jack stands (in addition to the jack) to secure the car with the wheel in question up off the ground about a inch or so off the ground PLUS a wheel choke to block the other wheel at the other axle. Then take all the lug nuts out of the wheel you want to remove and kick the tire part of the wheel with your feet (with shoes or boots on) while you are sitting down on the ground facing that wheel? I have done this once a few years ago trying to remove a wheel that was "stuck" to the axle.

Good luck.

I lost a wheel completely when some joker took the nuts off when I was parked (car had studs and nuts rather than bolts). But that was a long time ago.

If you loosen by just one turn then lower the jack and see what happens. you can get more extreme by degrees until you get sucess.

As an aside, I took one rear wheel off this week, to reposition the mudflap. I'm impressed with the jacking points, the rear supension design, the wooly stuff that lines the wheel arch, everything.

Do not load up the wheel with the lug bolts loose!

Jack the wheel, remove the lug bolts and use elbow grease, or give it a good boot near the edge of the tire, work it back and forth be patient and it will let go.

Every year when I replace my winter wheel/tire setup I run into this problem, It's just got a little rust and corrosion on the hub.

Best of luck

Why not - I've (as have several other people here ) done it loads of times, on several different vehicles, with no adverse effect. We are just talking about loosening the fastenings by a couple of turns, and just rocking the car back & forth, or moving the steering, not driving a couple of miles with them loose.

As a corollary: once the wheel is removed, remember to apply a very thin coat of high-temperature grease at the interface between the inner surface of the rim and the wheel hub to prevent future difficulties.

Its a chemical reaction between the alloys and the steel rim. Give the back of the wheel a few belts with a lump hammer / mallet going from one side to the other. Then as above apply thin layer of grease. Happened to me when I was painting my calipers, the wheel would not budge, after much huffing and puffing and bating it came off ( no sniggering down the back please ). The other 3 wheels were no problem.

Well, I use zinc anti-seize on all my cars - works a treat. I also use the "loosen the lugs" a turn or two to break them free. I've got a picture of an almost new Conti with a nasty sidewall bulge caused by a jacka$$ with a hammer and no patience!

? ? ? ? ? ? - You haven't run over a sheeps have you :eek::eek:
Nope. I had to stop quickly yesterday to avoid a fox that was looking the other way. One of these destroyed the front end of my Smart a few years ago. And I do get rabbits and badgers to aim at. Fortunately no mooses.

There's a fibrous lining to the wheel arch - presumably a noise supressant. Seems to be better stuff than I've had on lesser cars.

All of the above will work

With it jacked up and the nuts slack you could also carefully spray wd40 where the wheel meets the disc ( Take care not to get any overspray on the pads ) leave to penatrate overnight and try again the next day

I've also had success with the boot removal systemt mentioned above...kicking rewards works (ie back to the car) or laying on the ground. You should only loosen the bolts in both cases...you may just knock it off the jack!

Sounds very "lumberjack" but cut a length of 2x4 or similar the diameter of the wheel. Helper holds it in position whilst you pound the wood with a mallet (or back of an axe/hatchet...we're a woodsy lot over here). Won't damage the rim, saves the tire sidewall...

The easy way is take to a tire store or to the MB dealer. Don't take chances hurting yourself or damaging your car.
