Need some advice on fixing the truck...
 

Ok so I just payed a mechanic hundreds of dollars to replace a fuel pressure regulator, u-joint, ABS sensor, and my stainless steel ABS line that blew in the process...

I still have to replace the Idler arm, the front right hub bearing, the MAF sensor, and an O2 sensor...

Would it save me a lot of money just doing the rest myself or should I just have the shop do it? Are any of these needed replacements especially difficult to do?

Thanks guys

EDIT: Forgot to mention it's an '01 Blazer LT

Well,first off it seems that you are paying FULL retail for this mechanic work! Which is is INSANE!-find a better shop! Anyway the idler and the hub should be done by a qualified shop as special tools are needed,and an alignment will need to be done afterwards anyway..with parts at retail-maybe $300 no more! I had the idler & pitman replaced with an alignment for $188! The MAF sensor and the O2 sensor can be done in your own garage for maybe $200 and about 2-3 hours time! Shop around!

another thing to do if you have a mechanic do it is buy the parts ahead of time. especially if you know what you need. mechanics mark up parts they put on vehicles. heck i know i do. it will tick off 99% of them but it will save you some money. i would look for a good local mechainic. i would say you go could do everything except the idler arm. i'm pretty sure there is an article for the wheel bearing and the maf sensor is a piece of cake.
