cleaning the wheels on my 997 C4S

[Black80XSA]

Unless you are using a VERY good quality trolley jack you should (editted []) NOT be lifting both wheels off the ground at once. the jacking points are pretty small to start with, so any slippage is expensive []

Leaving the other wheel on the ground, even with little weight on it will stabilise the lift and share some of the load. Professional jacks with bigger lifting plates are perhaps more suited to lifting both wheels clear

Is there a 'not' missing in your reply ?

I also think one wheel at a time is the safer option.

Not sure why raising car on jacking point an extra couple of inches (that is literally all it takes) would put extra stress on chasis or jacking point. You still change one wheel at at a time just only jack up once

Here is another one that may be controversial. When I wash my wheels I always wash off the discs as well to get the brake dust out of the drilled holes. I then find when I drive the car to dry off the discs the wheels always get dirty again which is frustrating as you effectively have to clean them twice. I have recently started drying the wheels and discs with my garden blower and it seems to work a treat. I still drive the car to make sure the discs are completely dry but I dont mess up the wheels so only clean them once. Can anyone see a problem with this?

how much should a good trolley jack cost? i'm looking at toolstation.com and they are showing a 1.5t lifting capacity trolley jack for £13.62????? I expected it to be more....

Snap-on Tools are doing a special deal at the moment - a 3 tonne trolley jack with 2 rachet axle stands at £139+Vat. Jack has a rubber jacking pad to avoid chassis damage and a low reach that is ideal for Porsches. It's the best you can buy for the money. Part No. is SNX300TJ
I would be wary of removing 2 wheels at a time due to risks of slippage. Also, on replacement the wheel nuts need to be tightened to the correct torque with a special torque wrench.
If you're unsure, it's probably best to get the wheels checked professionally.

It is not possible to jack a GT3 from the rear jacking point without the front wheel becoming airborne.

Dont forget that you will need a torque wrench as well.....................

 

[bobfair]

I would also recommend use of a soft socket and wheel assembly pins (shown in the handbook but not supplied) The soft socket protects the wheel and bolt and the pins make it much easier to relocate the wheel properly.

So there we have it. If like me you have your wheels off every couple of weeks you will need a good quality trolley jack preferably with soft jacking plate, a soft socket, a breaking bar, 2 wheel assembly pins, a torgue wrench (correct torque for nuts is in hand book). If however you are like most people you clean the wheels on the car then forget the above

I would try not to use your Zymol wax on your wheels. The reasons for this are the high temps of your brake dust will soon melt through the Carnauba wax and also the waxes are not on the cheap side.

I use sealants like Car lack 68 and Car Lack Sealant

Or Klasse AIO and Klasse SG

Both are well priced, work well at high temps and go along way meaning you have more Zymol wax left for your paintwork.[]

I get my from www.carsparkle.co.uk

This is supposed to be a simple job !

I am just going to apply the tried and tested 'carefully does it' method with my standard tools !

 

[bobfair]

Fair enough Yves but if I were you I would make sure your standard tools included a torque wrench as under or overtightening wheel bolts can have serious consequences

I'm with Bob on this one, I have a sleeved impact socket (shame the OPC didn't use one) and torque wrench from Halfords (about £60 from memory) and using it makes you realise how easily you can under or overtighten the wheel nuts. I was from the old school of nip the nuts up, fully lower the car then jump on the wrench (14st) for that extra "pinch". If you are using an 18" lever that can impart some serious torque, way more than the 90 odd ft/lb (I think) required. Similarly, using a typical 12" OEM type wrench, unless you are particularly robust, it takes some effort to impart the necessary torque, just by using your hands (I believe they are supplied that size to stop people from overtightening?).

Also, get the aluminium wheel alignment tool, I keep one in my drivers door pocket. It makes dropping the wheel back on a piece of cake. Try it without and you will be clanging the calipers against the wheel, trying to line up the holes to put the bolts in and balancing the wheel on your knees (they are really heavy - especially the rears). Got mine from the Porscheshop for a few quid.

With regards the trolley jack, mine has a solid metal "cup" with 4 slots in the rim, which if positioned correctly lifts the car, front or rear without any problems at all. You shouldn't need a massive load bearing unit as there is probably only 3-400 kg load anyway for a single wheel lift, so a 1 tonne unit should be fine? NB: Do not be tempted to slide under the car for a look or fiddle around (I find it very tempting) without some properly positioned axle stands or similar.

Another word of caution, I followed all these procedures a few months back, to thoroughly clean my wheels, and while re-filling my bucket, the front O/S (which was leant against the wall at about 30 degrees) toppled onto it's front face, wrecking the paint and so defeating the whole object of the exercise!!

bob,

You can count on it !
