Mmmmm, it's a little tricker than it looks. The bolts surrounding the front cover are removed, then a couple of the bolts can be threaded into those 2 threaded holes and the whole front cover removd, that's easy enough. Those bolts are torqued to 13nm.
There are 2 teflon seals on the back side of the pump you have to be careful are kying flat in their groove when reinstalling, recommend you you bearing grease as a "temporary adhsive" to reinstall. Main problem, as you'll see is a ring of springs that needs to be compressed to remove a snap ring. Tool # 201-589-12-43-00 is almost a requirement to do this, unless someone else can advise. Once that's off, you can pull off what they call the plunger, it's the barrel shaped thing with the wide "fingers" pointing up. You can decide to replace the seal around the plunger or not, maybe not a bad idea. Then you can disassemble the pump itself and replace the radial seal on the pump (be sure to inspect the bushing in the front pump, if it's trashy looking you might want to consider a new pump) and also the o-ring surrounding the pump is probably the leaking seal you need to "really" replace. The bolts holding the pump together are torqued to 20nm.
