I'm going to tackle rear shock repalcement on my 99 ML 320. I have been pouring over the various excellent threads and think I am ready.

I'm considering buying an impact wrench. Sounds like (especially from Ron in SC) that an impact wrench can make this job a lot easier. Lowes has a 220 ft lb model for just $29.00. Do you think this will be adequate, or will I be wasting my money? If 220 ft lbs isn't enough, how many do I need?

I don't do that much wrenching (I'm more of a homewrecker), but it would also come in handy to drive lag bolts in ledgers in my deck business.

Also, I have a 13 mm combo wrench and a cheap ratcheting box wrench set. The box wrench is not offset. Do I need an offset 13 mm? Would the flex head gear wrench be worth the extra investment over the fixed angle offset?

I don't have a torque wrench. Was hoping not to have to buy one. Can I get by without it? And how do you torque those top three 13 mm nuts in that restricted space anyway? Perhaps I can borrow or rent one if you guys think it is mandatory.

TIA for all your great information.
