Hi,

So - just got home with my new car and wanted to see how I can change wheels. To my surprise I could not really understand how by just looking under the car. I didn't locate the lifting points.

So drove to skoda and asked them, how do I use a trolley jack on my new car?

Guess what their answer was?

"We're not allowed to tell you because you're not supposed to change wheels yourself"

To say the least, I was surprised.

So anyway. Under my car I have 6 weird things that looks like bowls with a peg onside of it. See picture:

How the heck am I supposed to use a trolley jack on that?

This may help, I'm looking at getting some but want to make sure there right first

page 216 indicates where to put the normal jack that comes with the car (when you spec a spare wheel). I have used a trolley jack to lift it at the same spot, obviously fitting a rubber pad on the trolley and you need to be careful not to damage the sill or anything between the sills and the chassis.

 

As for the dealers answer..I can only assume he worked for Boeing or something similar before. You may need to remind him that he doesn't sell jumbo jets or formula one cars.

I have read the manual, but as you say it only states how to use the original jack. Not a trolley jack.

Now even if I'd put say a hockey puck on my trolley jack I still don't understand how to lift the car. The surface of the hockey puck would not be "inside" the bowl with the peg. It'd be on the plastic surroundings of the bowl with the peg - which I assume is no no.

Very confused...

so am I now

 

When I changed the wheels, the trolley jack we used had a surface diameter of about 10cm. The rubber bit was barely a few millimeters, but putting in under the car exactly under the vertical metal sheet where you'd put the normal jack, it didn't touch anything else (sill or chassis or cables) and we just lifted it up.

I'm assuming that what you have photographed is the possible fitting position for chassis lifting pads like what audis have. I'm sure someone more knowledgable will know if this is correct or not

This is the same way I've done it twice now, with no problems what so ever. Just make sure your jack pad is soft enough so it doesn't put any unnecessary strain on the lifting point. (They are easy to locate by looking at the arrows under the door sills.)

Use a pad and jack under the strengthened vertical section of the sill.

This is exactly the same method I use.

I've done exactly this twice now with a cheap trolley jack from the Swiss equivelant of B&Q.

I don't use anything as a separater but with careful placement & first engagement of the jack I don't have any noticable marks or breaks in the sealant.

Seems to work fine for me.

Where exactly is this "vertical metal sheet"? I've looked under the car, but all I see is plastic - and those bowls with pegs that i've already posted a photo on.

Would someone perhaps have a photo of that vertical metal sheet you put your jack pad on?

 

Thanks,

Nevermind, I think i know what you mean now. I took a picture of what I believe is the correct jack point;

So, what I've marked in yellow is the metal sheet you're talking about - right? This is the jack point for the original jack - I assume.

 

So what in this actually takes the weight? Is it the top of the lip, the green arrows in the picture?

Or is this lip actually resting in "air" and the weight is distributed where this lip actually bottoms - the pink arrows in the picture?

 

Vol

That's it.  The load is taken at the bottom, where your green arrows are.  That section of the web is thicker, strengthened to take the load.

 

Personally I suggest a hockey puck (or wood block) with a groove cut in it, but others have not cut a groove and had no trouble.  I've even read of someone using a thick wad of folded news paper which worked fine.

 

The other post I linked shows where points exist to put in lifting points which can be bought after market, or from Audi.  They are it seems designed for a four point lift though not a trolley jack and using them with a jack can push them up into the locating holes too far.

Right - thanks neiln for confirming this.

 

I'm still somewhat confused about one last thing though;

If the bottom of this lip is what should take the load - Why would you want to make a groove cut in the hockey puck at all? To me it seems like it would make more sense to have the hockey puck as is - so that it actually puts the load at the very bottom and nowhere else?

The groove is to centre locate the puck. I'm looking for a jack with a pad on the lift point on it at the minute

Wait, what? :-)

 

Vol

Here mine , i use them on my Nissan , same design for the jacking point

 

So let me get this straight.

 

The only reason you're making the groove in the hockey puck is to "help" finding the centre of the puck?

It makes no actual difference to a non modified hockey puck then?

 

Vol

Locate the centre of the puck, spread the load ever so sightly, and mainly to remove the (probably slight) chance of slippage.

Centre, agreed.

Slippage, agreed.

 

Spread the load however? How is that possible? As far as i understand, the very tip of the lip will touch on the hockey puck - right? How does it matter if tip of the lip touches the bottom of the groove, compared to just touching the hockey puck as it is?

Yeah true, no not Really

If you don't cut a groove you'll bend the lip flat won't you , the grooves on mine clear the lip on my Nissan totally , they stop the stands/jack from slipping and stop anything scratching the paint under the car , easy fix

I understand your point, but as previously stated in this thread it IS the tip of lip that has all the weight. Now, unless that statement is untrue it would make no difference using a groove or not on the weight distribution, now would it?

If you look along the sill where the dimpled surface is you will see a downwards pointing triangle approx an inch in size. This points to the jacking point under the sill. I use a trolley jack with a piece of soft wood on the cup approx 6 inches square, have done since moved into up to Buxton in 1998, change the wheels every winter on both cars, never had a problem.

I know it seems odd, but yes the octy will is designed to take the weight on the bottom edge of the vertical web.  The web is strengthened at each jacking point. On this, please don't be confused by the well meaning but uninformed Nissan owner.
