Have bought the pusher to dismantle at my Audi A4 Bj. 2003, the clamping screw. Here is equal noted the pusher adjusts the built-axis models only with Stahlradträger, but there is deduction, because the product description does not match. In my case, Aluradträger, you can only use the pusher when fully expanding the knuckle and the wishbone bolts saws off the top. Due to the shape of Aluradträgers can start the releaser so only from above. The actual terms of the bolt then just work that way. The temple has significantly bent during the squeezing, also the threaded bolt was something squashed. This thread has still works, but I do not know how looks like when you have so many words, the clamping screws. In my case, there were just two. For the additional deduction.
All in all, and in terms of price, a usable product, when you know what and you can use it and noted the limited shelf life.
