I like the new subframe, but I am not quite there to spend the money on it.The ass end also moves around because of toe movement. Everytime you are on or off the gas, or even hit a bump, the rear toe moves in and out causing unsettlement. It’s not a huge deal, just something you need to be aware of. The new subframe will eliminate this.
The part came today, despite in the description it came only one part, but the price was still ok. I started to disassemble the wheel hub and thought I came to a stop when I saw that 30mm axle nut. I did not have a deep 30mm socket and thought this nut must be torqued quite a bit. The 30mm socket I have just barley touched the hex. Anyway, lucky me I was able to losen the nut. It was hand tight, not more. Now I wonder was that the reason why I had play? I don't think so, but wanted to be sure.Bad bearings will have play, time to replace.
The Goblin (Cobalt) wheel hubs are a sealed unit, not a spindle with races and bearings. They are replaced as a whole unit - the Cobalt front bearing hubs are on the rear, so you would need to order a front assembly for your bolt pattern (4X100?). If one is going bad, its time to replace both sides before the other side starts to fail, so order 2 of them.
They do require some disassembly of the suspension pieces to remove from the aluminum uprights - either the strut bottom mount bolts or the ball joint (not sure which would make for an easier process?). The bearing hubs are held in by 3 bolts on the aluminum uprights. They can only install one way. Once you have them, be sure to ask questions and post photos if you need help.
I don’t remember what the actual torque spec is for the axle nut but if it comes loose it will make the bearing looseThe part came today, despite in the description it came only one part, but the price was still ok.

Another question, please have a look at the picture. The nut is oriented in the way it was installed. Is that the right way??View attachment 46401
I think I used the "higher" temp engine paint or maybe it was brake caliper paint without going to exhaust temperature paint. Going on 2.5 years now and has held up well. But it doesn't get driven in the wet, and probably rarely gets the brakes real hot since it's all backroad driving.Exhaust high heat paint would probably work.
Or a coating may have been applied and it just looks like raw steel.I replaced the hub now anyway, the old hub definitely has play while the new one has no play. I will torque them to 210Nm. And check the other side too.
The painting of the rotors is a good idea. I wonder why at my BMW the rotors are not rusty, might be a different material.
