Replacement Scissor Jack
« November 17, 2019, 06:17:25 »
Went to put my winter rims on, using the toy scissor jack in the standard kit, and (un)fortunately noticed it twisting at the top. Damage was the underseal torn off exposing the body underneath. This jack would have been used maybe 20/24 times previously. Rating 700kg.
A search reveals the available scissor jacks with the same fitment at the top, to fit around the seam weld, are only rated 1000kg/1t, are are similarly 'cheap', @10 at the lower end to 20 at the upper end retail, but all identically puny.
A much more substantial 1.5t scissor jack doesn't have the fitment to locate it by the seam weld, nor a flat top, so would dig into the underseal. I'm not entirely sure the fitting at the top is necessary, but it is useful to locate the jack correctly.
Having a look underneath, the jacking points are about 5cm deep, and 7cm wide, a bit smaller at the front. The top of the scissor jack meanwhile is about 4cm square where it touches the jacking point.
So, being unable to source the right scissor jack, I bought a cheap 2t trolley jack that came with a circular 7cm diameter rubber shoe. I used a piece of wood the same size as the jacking point to avoid the seam weld (by lowering the contact point to below the seam) and to locate the head of the jack centrally under the wood. Worked a treat, however still leaves me without a scissor jack to carry around.
I'm not going to buy a Hyundai jack, and want something I can trust, so it's going to be a 1.5t jobby.
(Although if it does become the emergency jack, it will only be called upon once or twice  :undecided:) This leaves me with having to locate a piece of wood or rubber on top of it to avoid damage and spread the load up to the size of the jacking point.
Who's done what with regards to scissor jack replacement?
I used my old mk4 golf standard jack for 12 years swapping rims twice a ear, never had an issue, so unhappily surprised with Hyundai tbh.

I've never had a scissor jack fail.
I do have a cheapie I bought at an auto accessories place which fills in as a spare around the garage. It's fine too.
I also have a small trolley jack and use a piece of pine in the same way as you are suggesting.
A basic one should be fine as long as you're only lifting one corner at a time, not the whole side.

If I didn't know better I'd think this was a jacking off competition...  :whistler:

I looked the flimsy piece of sheet metal which is bent in to a shape of a jack and made a decission to never use it. Threw that one away and bought a 1.5 ton scissor jack for possible spare tyre changes. I bought a jack which has the notch on the top, so it work on the same lifting points as the oem "jack". That is only for emergency use (spare tyre). Summer and winter tyres I change with a 2.5ton hydraulic garage jack. I have a piece of 2x4 wood where I have cut a notch for the seam, so it can be used to the same lift points as the scissor jack.

So I bought the 1.5t scissor jack.



However, jacking up the car, the same phenomonem occured! The jack appears to start leaning, however not so pronounced as with the small jack.
Maybe it's an optical illusion, because I cannot see the new jack having an issue.



Terrible picture I know.

Cut a notch in the 2x4 so it sits over the jacking point/seam and line the jack up correctly so the pivot points lean with the car.
