Aftermarket parts

[a_kelley]

Wtf. I've been dealing with this certain supplier for five years.. I've bought probably twenty or thirty rack& pinions.. installed a leaky one two days ago. Do they not pressure test their rebuilds before shipping? Same thing with pumps, I've gotten 2-3 faulty in 40 or 50.... but no one is ever surprised when I get one defected out. Is qc really that bad? I mean, I could reseal racks and pumps but the reason I don't is for the warranty.. are reman motors and transmissions from parts houses the same way? If so I'd sooner build them than outsource it and just eat it if something went wrong..

I don't think they do any significant QC checks. I've had water pumps with casting flaws that leaked and some remand that were cracked.

Last year at work we had a 20" gate valve that when we leak tested the system, we found a 1/2" hole in the casting.

Most place's spec is to QC check like 10% or less. It's a matter of their warranty and failure rate and cost to make their parts better. Pretty typical. I've found myself buying parts now that state 100% factory leak tested, etc. that way I know I likely won't have to do my work twice because of their faulty part.

You better do your own qc. I replaced a Pittman arm , steering was off, thought it was my fault, got another and compared to original and it was clocked wrong. Got one from a different source and it was correct. Sure I got my money back but can't use a puller unless steering box is unbolted and moved. What a lot of work. Tried to contact home office of first supplier to advise them of defect and prevent others the unneeded aggravation. Not possible. How about a defect distributer cap on a big block Suburban? How about the wrong pump in a brand new Delphi fuel pump assembly? Have to test parts when possible before installing or risk doing it twice.

QC is often done on X number of samples per batch, instead of every part. Depends on how critical the part is, and how statistically cost effective it is to exchange the small number of defective parts versus spending more money to test every part and then having to pass that additional time and money per part along to the end customer. Sucks, but that's the way it is when you're running a low-margin reman business like that.

I have never seen as many parts failures in my 15 years in the business as I have in the past year or so. We are just finishing (or attempting to finish...) a '73 pro-touring Camaro build at the shop and have had numerous parts failures. Now I don't expect everything to work just right on a build of this magnitude, but so far we have had 2 bad aftermarket alternators, 2 bad aftermarket horns, 1 bad aftermarket headlight switch, 1 bad aftermarket dimmer switch, 1 defective new brake booster, 1 bad fuel pump assembly (built by aftermarket tank manufacturer), 1 set defective plug wires (rated for 600*, fail at 340*). That is all on one project and I'm sure I am forgetting some things.

I do my best to steer clear of certain remanufacturers due to numerous mis-machined, mis-boxed or just poor quality parts, but damn I am about ready to stop selling parts all together it has gotten so rediculous. If we can rebuild or build something in house, I will take the extra time to do it so we know what was used and how it was done.

Agreed. We moved our business from advance a few years back because failures were outrageous, they've cut every corner possible looking for the cheapest parts. We've not had nearly as many failures from NAPA. I fid that odd, considering many parts are sourced from the same manufacturer.

It's possible they are getting better pricing by accepting a higher failure rate percentage from the same reman manufacturer.

Or its a different reman line or different facility under the same company.

That's been the most common thought among shop owners. Advance auto is no longer capable of supplying professional shops, not that they ever were.
