I have to agree with Bdcardinal. You need to get the right tools. Trust me, if you have to buy another wrench, you'll end up using it again later. I don't think I've ever bought a tool that I haven't used at least 5 times.
I am most likely much older than most of you. I am almost 58. I began buying tools when I was a teenager. Of course, then my funds were limited so I had to get by with what I could come up with, but as years went forward when I needed a tool I somehow came up with the money.
In many cases I would buy a tool for more money than it would cost to just hire the job done. My thinking was that by doing this, I then had the tool for next time. Now that I have been collecting tools and equipment for more than 40 years, there is very little that I don't have.
I have everything from a two post lift, to my own computer wheel balancer to welders and on and on. I still have lots of collecting to do, the Lord willing, because I expect to spend another 25 or 30 years working at it.
When these jobs come along, find a way to buy the tools you need, put them away securely and take care of them. It will pay off in spades.
BTW, DO NOT use the torque wrench to remove the nut unless it's cranked up to OVER the amount that's needed. It can/will ruin the wrench. Use an impact or breaker bar to remove the nut, a torque wrench (or some creative math) to install it.
