Bmw jack failure

Eins Suchtig · 03-09-2015, 08:38 PM

While changing my rear calipers, the jack failed.

Long story short. I lifted the car with the jack, put 2 stands, lowered the load in the stands, removed the wheel, replaced the caliper. Then put he wheel back, raised the jack to relieve the stands, removed both stands and when I moved the lever to start lowering the jack, the car suddenly felt. Luckily nothing happened. After inspecting the jack I found it stripped the threads of he cylinder were the big screw threads in. The screw seems intact, but shows a lot of metal shavings from the cylinder.

Has anybody experienced this type of failure? This is the jack that comes from BMW as a kit with a torque wrench, lever, nice carry bag, gloves,...

Not a BMW jack, but a new VW jack did the exact same thing, I would imagine the top four German car manufactures source their jacks from the same factory.

Thats what happens when you use an emergency jack for service work.
