I had a couple days off so I scheduled the lift at the club I belong to and knocked out the left front outer cv boot, and an oil change. I broke down and bought the tool to pull the axle back thru the hob…some of the best money I have spent on the x5. I hate specialty tools, but this one saves a lot of time and PTSD.
The axles are only 2 years old and the outer boots are failing, but it was a pretty easy job, by X5 standards. I knocked the axle out of the hub assembly with a drift, and the reassembly tool really helped speed that part up. The CV joint was fine so I didn’t have to disassemble it. Just knocked it off the shaft, cleaned out the grease, repacked it and put it back together. The axle popped right back into the diff with just a bit of pressure….happy day. I think I can reassemble and torque the front end suspension and brakes in my sleep now. The right side outer boot is cracking at the small clamp too now, so I’ll tape that up and see how long I can push it.
My X5 takes about 9.5 quarts with the oil cooler. I drain the cooler too just to make sure I get as much old oil out as possible. This oil had about 5k on it, which is about 1k more than I like to go, but it looked fine and the filter hadn’t trapped anything shiny or chunky. I sent a sample off to Blackstone for analyzing. Mostly because I think it’s cool to read the report. The motor has about 14k on it, and I did a sample last at around 4k. Just after my overheat adventures.

Can you link me to this tool? The last time, I hammered a block of wood on the ring of the hub. It worked but took forever. It was very loud and destroyed two of my good wood blocks.
The air hammer with tapered punch is amazing to get them out of the hub. Would recommend.
Myself .. I have everything apart. The front subframe is ready to come down. I'm just not sure about this strange front bar under the front bumper with these two pipes sticking out into the subframe. It looks like it's going to be a problem.
I'm currently multitasking between hammering the lower ball joints out of the steering knuckles and degreasing the engine with the accessories and oil filter housing off. That engine degreaser stuff works really well. I've been sleeping on that just using brake clean the entire time. The stuff is awesome.
It's been a tennis match between the smell of the degreaser and the noise of the hammering,. These ball joints are an absolute nightmare. Fortunately, all the bolts came out fairly easily they're just super seized in the knuckle. Worst part of the car to work on. I have the ears all pried out and folded down but I can't get the middle thing to even move yet, day 2.
