Why is my truck shaking and popping after replacing wheel hubs?

“I had my front-right lug stud replaced and when I got to work noticed my rotor was a lot more shiny than it was before. Then I noticed huge gouges in the rotor.”source ↗

“Replace both hubs and bearings, was driving home from getting an alignment and heard a pop then the truck started to shake. the nut is torqued to spec 177ft lbs. the glitter makes me nervous”source ↗

“Am I wrong in thinking that something fell in when the changed the harness?”source ↗

“Really expensive, nasty sounding noise coming from the front end of my 1999 bmw 323i.”source ↗

“now when driving forward slowly it makes this nasty different sounding noise”source ↗

“about two days later I started having an issue where multiple warning/error lights suddenly come on while I’m driving.”source ↗

“I also personally noticed that the brakes feel different since the compressor replacement—the brake pedal feels noticeably softer/looser than it did before.”source ↗

“Now they are also saying that an axle is bad because the threads are damaged. Sounds to me like they screwed up when removing the axle.”source ↗

“They said from what they saw they couldn't see any other damage to any engine components but I'm sure they didn't look at everything.”source ↗

“So they said it was a spark plug, I asked for them to send me a picture and then they said they meant my old spark plugs. I still have my old spark plugs and they're not damaged at all.”source ↗

“To me it sounds like that they are trying to cover up for the possibility that something fell in the intake while they had it apart.”source ↗

“They said from what they saw with the scope there doesn't appear to be anything damaged in my engine outside of this. If my engine blew up then so be it and I'd eat it. But the guessing game is killing me.”source ↗

“they just called me giving me an update and said that the check engine light is on, and to diagnose it would be $200.”source ↗

“I literally have been driving this car for 2 years and even up until last night, the check engine light has never come on.”source ↗

“Am I supposed to just believe that it’s some massive coincidence that it came on while it was at the shop or am I getting scammed? I’m not sure what I’m supposed to do or believe”source ↗

“Looking for outside opinions before I spend more money.”source ↗

“Sept 21, six days later: system stopped cooling.”source ↗

“If a proper whole system pressure test was done on the 15th, should it have found a leak at a condenser coil joint?”source ↗

“It feels like it should have a decade.”source ↗

“So I had an issue with my condos AC unit where it started making a weird sound right after they did the coil maintenance / clean out.”source ↗

“After some googling, I found that checking the actuator is a part of their maintenance, so now I’m just wondering if its possible that they’re at fault here and just not taking accountability, since we don’t know any better.”source ↗

“Now, out of warranty, the unit shuts off before the blower starts. The furnace is also fairly warm to the touch at the top.”source ↗

“So is this repair “legit?” Am I screwed?”source ↗

“I was concerned that the repair let in an abundance of dust and dirt that finally became too much.”source ↗

“My son was driving and his car just quit. He pulled over and saw that oil had come up through the dipstick and went all over the engine.”source ↗

“Im worried the engine may be seized but it still has oil on the dipstick.”source ↗

“Hi can someone help me figure out why my cars is throwing out these codes? I recently replaced the turbo and the engine.”source ↗

“driving home it is still making the noise. I don't know where else to look.”source ↗

“I really know nothing about cars & feel like I changed break pads for no reason as he said they were actually fine.”source ↗
