Hello, I only changed the winter tires today (I didn’t get there sooner due to a stay abroad). I noticed a “cracking and I have the feeling that the car jacks have bent a bit at the front of the two car jacks on the rear axle. Has any of you already experienced similar things? I have used such a universal car lifter, which I already used for another, smaller one. Do you think this is normal or have I done something wrong or even broken? Can you do anything wrong if you place the jack correctly at the jacking points? I have attached some photos. Do you think this essay is more gentle for the car?https://www.amazon.de/…/ref=mp_s_a_1_1?__mk_en_DEÅMÅZÕÑ&qid=1530739441&sr=8-1-spons&pi=AC_SX236_SY340_QL65&keywords=car lifter+rubber pad&psc=1 Thanks a lot in advance!
