Im under the mindset that if I dont need to buy a new expensive tool that I will probably never use again than its not worth doing it yourself

I actually prefer going the DIY route especially if its going to save me a crap ton of money. The most far out DIY I did was installing a new canvas top on my E36 convertible, and that was a bitch. Ive never done anything that involved removing parts of the engine because im afraid I wont be able to put everything back correctly. Having said that, I still think I can do the valve cover gasket if I take my time - but when it comes to the control arms/axle I might have to leave that to a mechanic because there is too much going down there and being so unfamiliar with "torque" im sure something will go wrong.

The left axle was already replaced because the boot was fully torn. So is the right, so im sure that whole axle will need replacing too
