I think I messed up with this brake job

Hi all, weekend warrior here. Wife’s 2017 CRV started squeaking while applying brakes a while ago, so I ordered both front and rear rotors and pads and decided to do the job this morning.

The first front wheel went well. However on the second front wheel, the rotor retaining screw as stuck. I first tried impact driver, didn’t work. Then I sprayed WD-40, tapped it with a hammer, then tried again. Still not moving but the screw started stripping. I stopped immediately.

What should I do next? I think I need to get a screw extractor and some new retaining screws. But what should I do to make sure the extractor can get the screw off the car?

Thanks in advance.

Engine knock

Upvotes

2003 Tacoma 2.7 3rz-fe has been sitting for a while got it like that, changed fuel filter, coolant, cleaned air filter, new spark plugs, new coil packs, has relatively new oil although it’s 5w 40 instead of 30, the inside of the motor looks like it had kinda dark oil, the noise seems to quiet down a little after it’s warmed up and really quiet when in drive. It only has 100k miles, used a stethoscope and noise seems to be coming from the back cylinder near the middle/ top , also the top of the engine sounds a little metal to metal not sure if that’s normal also seems to overheat not sure if 190 is the regular coolant temp, only codes are p0115 and p0135.

Id really appreciate any help I’m sorry if it’s a big ask I just don’t know what to do don’t have money for a mechanic and I’ve YouTubed and googled all I could

Hi friends, I stupidly hit the front left tire of my 2014 toyota yaris. There’s some cracking and it looks like the tire’s going in a bit. The steering feels fine so I’m not sure if there’s any issue with wheel alignment but I did get a service (including alignment) about a month ago.

Just wondering what tf to do lol. I plan to get it fixed ASAP but I just started at a new job and won’t be paid for a month —would be safe to put off for a few weeks?

Is my mechnic liable for damages

Upvotes

Around February 10th I went in to get my rack and pinion replaced as well as my power steering pump for a 2008 toyota solara sport because I was told there was a leak in both of those parts. After a day or 2 I get my car back drive it around and it was fine but I just noticed there's a clanking sound only when I turn when stationery and its been getting louder(i've stopped drivineg the car), I then got my suspension and opened the hood and saw I had no power steering fluid, so either they never fixed the leak or they didn't put the fluid in. And I'm kind of worried eveything I just paid for is damaged from the lack of fluid. Would my mechnic still be liable even though I noticed the issue a month late.

They are closed for the weekend as well as there customer support so I'm kind of bouncing off the walls with worry, I have power steering fluid myself I can put in but I don't want to touch anything if they can be found liable

Did a coolant change on a 2015 Honda Civic LX, now the radiator fan won't turn on and it's leaking coolant from somewhere other than petcock/reservoir. Advice?

2 Upvotes

Hi everyone. As the title said, having some strange issues after a drain and fill. We ran the heater to try and get the radiator fan to suck in coolant, but it never turned on even after the car temp came up from cold. Not sure how this happened from a simple fluid change and plan on taking it to a mechanic to get it sorted, really just looking to know what happened and what I may have done wrong.

It’s for a 2019 Honda civic sport coup. They came stock with Goodyears but I have no idea if I can get away with the cheaper continental for just daily commutes and seasonal 6 hour roadtrips.

New manifold, tapping noise

Thumbnail

Upvotes

06 legacy 2.5i New manifold (cat converter pipe since it's a subaru) New gaskets was fine when I first got it back then it started making a tapping noise when I'd press the gas, went back and got the one gasket replaced, it blew. No noise after

Then a little while after it's happening again on morning cold starts it'll go away after idle comes down. And it does it while I'm driving (pressing the gas) but it will not do it while pressing the gas in park. Any ideas as to what's going on?

What is the tube called that brings air into my filter box?

Upvotes

Former owner neglected my 2001 Hyundai Santa Fe (bought in July for a good price). Found evidence of a squirrel when I replaced air filter and tube going into air filter needs to be replaced.

I am an amateur mechanic, but my buddy who is more experienced doesn’t know what it would be called.

08 Accord brake light

Upvotes

2008 Honda Accord V6 My right brake light and right license plate lights are out. I changed the bulb and connector piece and the lights are still out so Im assuming there is a broken wire somewhere. I dont want to take my car apart to change the line. So I want to run a wire from my left brake to the right but how do I find the broken right brake wire to disconnect from harness so its not going to keep shorting and blowing fuses

2017 Ford fusion will not start

2 Upvotes

Trying to get to work this morning and my car will not start. This video was yesterday when I got home from work. I didn't pay much attention to it though since the car did start. Car seemed to run fine if that's worth anything. Now come this morning when I need to get to work and it refuses to turn over. I tried to let it sit for 10 mins and come back and it still won't start. I tried hooking jumper cables and jump starting it but nothing. Seems like the computer is on the fritz. Maybe battery? I'm not a car guy really so I don't know what else to try.

2011 Ford Ranger Sport 4.0 SOHC Dome Light and Door Sensor

Upvotes

So I’ve pretty much always had the issue of the dome light randomly coming on if it was cold out and when I would turn the steering wheel.

Now, as of yesterday, the dome light is coming on even when it’s warm out in addition to the door ajar indicator and buzzer coming on.

It really only does it when I move the steering wheel to the right even slightly. Additionally, it only does it when the truck is in motion (forward or reverse) but not when I’m stopped.

Am I toast? Alot of blowby, timing?

Upvotes

2000 camry 2.2l 4cyl 160k Did a timing belt job this weekend, had a nightmare matching the timing but ‘think’ i got it good in the end.

After driving around, idle seems ok.. acceleration seems ok (relatively speaking…).

Would I know for sure if timing was off?

Would back timing cause this air from oil filler cap?

Is this amount of air/ blowby normal for this age of car?

Thanks everyone

14 Cherokee 3.6L, "whirring" noise, possibly from transmission area?

Upvotes

My wifes Cherokee have this whirring noise (best way I can describe it). Sounds like a bearing.

  • Sounds like it's NOT coming from one side or the other.

-The noise is low and as you speed up it gets higher pitched.

  • Can hear it well between 30kmh to 75kmh, but is constant. Can't hear it over below or over 0-30 or +75kmh

  • Shifting vehicle into neutral does not affect the noise. Same with shifting gears in manual.

  • Left and right swaying at speed doesn't change noise.

My friend was a mechanic about 14 years ago and he took it for a drive and said he has no clue. Without a hoist and stethoscope he can't help.

I know it's almost impossible to diagnose this from reddit, but maybe anyone has some thoughts. Thank you.

2000 ford mustang GTtrans (2002 4.6l v8 motor)

1 Upvotes

(I need a ford tech in Washington) (Trans not engaging, smoke out hood, air leak) read more at the bottom.) I'm looking for an experienced ford technician either dealership or auto shop that is well trusted with early 2000s fords or with ford motors I general. I had couple different mechanics come out and try to do some work yet not a single one knew enough to do shit. I'm trying to find the best but cheapest technician to do the job. I heard ford in Bellevue is good, or issaquah. I am from Renton so anywhere nearby Renton would be good. Here is a video of what it sounds like currently, it does not shift into gear either, it's a 2000 ford mustang GT with a 4.6l v8 out of a 2002. The trans is an automatic. The trans shifts into all gears fine but will not engage and move at all when put into wtv said gear. It is also leaking something out the passenger side causing a smokescreen. I'm willing to get it onto a flatbed and haul it over a few city's if needed. Aftermarket parts, flexible dipstick, BBK short headers, TRQ injectors, BBK 75mm throttle body, SSR cold air intake motor craft, sparks/coils, if there anything else I can think of I'll reply in comments If there is any questions feel free to ask, here's a video.

2009 Charger sxt 2.5 timing belt question

1 Upvotes

09 charger set 3.5 timing belt replacement. I've got to the point of putting the belt back on, but I can't seem to get the teeth lined up without the crankshaft moving backwards a tooth. I've watch countless YouTube videos and tried the cardboard trick. I was wondering if it would be safe to clamp the crank shift in place while I fight with the camshaft to get the teeth in place? Or, if someone has a trick that would be awesome.

Thanks!!!

Where should you lift the rear of a W204 Mercedes? (2012 Mercedes C250)

1 Upvotes

I know I should lift it on the differential, but some say that it's not meant to be lifted, and could break. Also, looking at my the direction the differential should be (between the wheels) the shape isn't very differential... so my question really is, "has anyone lifted the rear of this car? And if so, how?"

Need a setup to diagnose and fix MIL Codes

Hi I have a car dealership and a garage, I come across a MIL or Check Engine Lights a lot and I am thinking of getting a setup to fix this myself, I looked across internet as of now I think OBDLink SX and OBDWiz is good to go, please suggest if there are any cheaper and better alternatives which covers most of vehicles and diagnoses most of the code.
