    Yep, counter clockwise from the back, clockwise from the front, swing under towards the passenger side (on Left hand drive cars). Just will not budge. Do I just need a longer wrench and bigger muscles? I've got the emergency brake off and the car in first gear to hold it.

    Picture of muscles?

    I hired the muscles for this job, haha

    At sub 150lbs, there's only so much muscle to go around. Bought the set of 6 large metric wrenches at harbor freight and got it off. Leverage made a world of difference even if you can only turn it 30 degrees at a time before the wrench hits the floor. (Working on Jack stands)

    Now for the torx bolts on the axles that are too close to the axle joint to get a socket on it. Time to Google around for some ideas.

    P.s. why do they love torx bolts so much?

    I suppose they are better than flat heads! I think its because torx/star tend to have a lot of surface area for the tool to grip, reducing the chance to strip it.

    Torx provide a larger clamp bolting surface area relative to the amount of torque one can apply to the fastener. They also take a small tool so there is greater clearance - this is important as modern car designs work to make more compact areas. As an example I remember the 80's Fox Mustang 5.0 exhaust manifolds had huge crimps in the runners because of the need to get the tools in place to tighten the exhaust stud bolts. It's why we see Fel-pro, for example, having torx head bolts versus the shitty hex bolts I just pulled off the QR25DE Nissan the other day in my garage.

    Torx are great, and if you are working on BMWs, I highly suggest full and complete sets of male and female torx sockets (shallow and deep) along with torx box end wrenches.

    A buddy and I swapped the rear diff yesterday… safe to say it’s pretty straightforward! We were able to do it without removing my exhaust or taking the driveshaft out completely. What a difference, the car is so much more planted through the corners now and it does great donuts ha ha

    Wish I had but I ordered the diff and tool when this was only 3 pages long.

    That wrench is also being listed as out of stock at the moment.

    Got mine out last night and will be shipping it back today.

    Can anyone recommend some box end torx wrenches? The external torx sockets I bought last winter for the clutch job were too fat to fit the torx bolts on the axles. A regular 11 point 3/8" box wrench worked to get them off but I'd like the correct tool for installing the new ones. Seems most of the ones I find are ratcheting which could make the wrench too fat to fit and then I'm stuck in the same situation. Just looking to hear from anyone else that did it themselves. Thanks guys. Can't wait to get the new one in.

    I used a 3/8” drive long female torx set with a tiny extension on my air ratchet. It fit all the way around. Swivel worked for most of it until I snapped it torquing them down haha.

    Like I said, I've got some craftsman torx sockets but they must have a bigger outside diameter than yours because they don't clear the axle/rubber boots.

    HP autosport decided to do the right thing and refund me for the faulty tool I received. Deleted my reviews and setting the record straight .

    Finally got a reasonably warm day yesterday so I got everything all back together and the summer wheels and tires on. Took it around the neighborhood and didn't hear or feel anything weird so I think we're all good. Just waiting on the core charge refund. Thanks again @doublespaces for doing all this.

    Going to need to replace these pilot super sports here soon so I'm on the look out for a secluded parking lot to try out the LSD with some donuts ;)
