Well you can check the prices on picknpull's website to get an idea. If there is one nearby I would start there cause it's cheaper than buying from individuals looking to turn a profit.

Helps if we know where you live??

Part outs on the Forums are great places .

Tell us what you really need rather then general stuff.

 

Also remember that good, used OEM parts can be much better quality and work more reliably than brand new cheap aftermarket parts.

 

^^ Second that!

 

Sometimes I agree with this, sometimes I don't. I worry sometimes that junkyard parts will fail in the same manner as my originals sicne they're invariably off of old high mileage vehicles. Good quality aftermarket is better than worn or rusty OEM..

Sometimes rebuilding your OEM parts might be a better course of action as well, I got very good at changing Champion afternarket starters last year while my rebuilt alternator hasn't missed a beat .
Look for OEM parts that are not being sold at the dealer, for example Beck/Arnley OEM ball joints are half the price of Toyota but the exact same part with the same markings.

At the end of the day if my original toyota parts lasted over 300 000km it really encourages me to buy new ones from the dealer when they fail.

 

Of course it can go both ways. That's why I said good used parts could be better. It is part and condition dependent. You don't want to find out your used part is not too far away from failing too! That would just suck.

I mention this because I have seen too many people come to this forum saying their starter went bad or something, replaced it with the generic $19.95 special parts store brand, and cannot figure out why the starter only worked for a week, only to find out the cheap starter they had just bought has failed...... for the third time....... in the same week.........

Beck/Arnley is a repackaging brand so you have to be careful and inspect what part you get. Sometimes you get OEM (which is awesome! ), and other times you could get a cheap Dorman part where duct tape and glue might be a better fix and last longer....
