Wow, I was failing to account for the fullness of the widespread incompetence there I guess...........
Crush till a solid hit sealing has been out there for 30 years now but you can't make up for a lack of a high school education.........or tighten it till you break it.
The auto parts places have empowered infinitely greater amounts of that as well with their totally retarded lifetime warranty policies that are not locked into reality at all. Why I quit the parts business, they were losing so much due to DIYer incompetence that they had to increase pricing almost every single week to maintain any sort of equilibrium. You can't get a raise for spit once the company gives all the profits to idiots who can't turn a bolt correctly then come crying to the store about 'bad parts'. Virtually every part I looked close at was either in perfect shape (wrong part picked out as the problem) or broken due to stupidity. Manufacturing quality usually had nothing to do with it. (Did any of you catch that, the CHINESE are now smarter than US) The biggest whopper of a problem the industry faces, they have no balls to contain it so your prices increase by the second. Only losers now buy over the counter, you are paying way, WAY too much in most cases. I got 40% off employee discount and that doesn't touch like Rock Auto now where often you can save up to 60% vs. OTC. Sometimes more. The manager used to get mad when I told her how much I saved by going online, she said I was not 'loyal' to the company. Pretty damn funny at the poverty wages they paid.
Take a popular part that is easy to break like certain water pumps with thin areas on one end of the casting to break easy and we used to scour the different stores trying to find one that was not broken in the box or missing parts. Sometimes all 20 or so stores had a bad part in their store, they just didn't know it until that search happened. They then shipped them all back to vendor claiming vendor screwed them up and why the vendors are now so upset with the chains, a real hate relationship forming there. Several times the vendors threatened to refuse all cores/rejects coming back unless the prices were allowed to go up. We got lots of damaged parts from the distribution warehouse as brand new when store employees hid the damage by putting back in box as good after customer railed on them when asked if he broke the part putting it on. Of course they don't, they NEVER do and the biggest lie I heard all day long.
Sorry for the rant..................a check.............if you run across another bad housing look closely inside the bolt holes, there will be threads cut if the part has been preinstalled before you to damage it. If no thread cuts then it's a plastic part, it could be manufacturing error, an injection molded part and popping the molds apart too quick before enough mold cooling occurs will warp a part like that. Any sliding mold there could be dragging too. As you can see I got damn good at determining where the problem lay, what with all the people coming in and claiming bad parts all day long. You got to where you could verify it one way or the other in maybe 70% of the situations.
