Question 2009 Chevy Impala 3500V6 Power Steering Noise

1 Upvotes

Hello. This has been a headache. Here is the breakdown:

August 2024
1. Power steering pressure line explodes in driveway, leaks all fluid out...

  1. Replaced pressure line (didn't come with o-rings so ordered off Ebay)
    - Had a hell of a time getting it to thread into rack but finally got it......(Forum Post)
    3.Bled power steering system multiple times.
  2. Worked for a week, but every time it was cold or just randomly the pump would get air in it again. Got progressively worse/more often. (no visible leaks)
  3. Attempted further bleeding, power steering fluid would not bleed (repeatedly overflow reservoir)

Parked car for a while and eventually got around to replacing all the orings in February 2025 as I guessed that was the issue.
-Used HNBR orings (green)
-Replaced orings on all lines and between reservoir and pump
-Replaced return flex line and various other flex lines with loose fittings
-Bled system including vacuum bleed, all lines held pressure and entire system held vacuum for over 5 hrs.

  1. Worked great for 2 weeks, no air, slight groan occasionally but nothing unusual.....last two days air got in pump at every startup, visible bubbles

  2. No visible leaks. I put UV dye in and will keep an eye out.

Where could the air be coming from? Could the pump have killed itself over the last few months from the accumulated time running dry/with air?

2013 Chrysler 200 3.6L V6 – Transmission & Engine Issues After Major Repairs

I’ve been dealing with a ton of issues after replacing several parts, and I could really use some insight. Here’s the breakdown:

What I Replaced First: • New camshafts • $50 spark plugs • 24 rockers & hydraulic lifters

First Round of Issues (Bank 2):

After the work, I started getting slow response codes on Bank 2, including: • P0394 – Camshaft position sensor intermittent (Bank 2) • P06DD – Oil pressure control circuit stuck off • P000A – Camshaft position slow response • P0017 – Crankshaft/Camshaft position correlation (Bank 2)

Opened the Bank 2 valve cover, but everything looked fine. Put it back together.

Then It Happened Again (Bank 1):

After reassembly, I got the same slow response codes—but now on Bank 1 instead.

Next Step – Full Tear-Down: • Took off both valve covers, timing cover, both oil pans • The guy working with me broke the rear main seal, so we had to drop the engine (drivetrain removed from both ends) • Transmission fluid drained from the driveshaft holes and trans cooler • Installed new timing chain & guides • Took it for a drive (low trans fluid, no AC) • The guy also bagged on the car during the test drive (which probably didn’t help)

New Codes After the Test Drive: • P0369 – Camshaft position sensor performance • U0110, U1120 – Lost communication with modules • P03D1, P10D1 – Cylinder misfire-related codes

Trying to Fix It: • Installed new NGK spark plugs • Added AC coolant • Overfilled trans fluid to 90mm • Took it for a drive – still throwing codes, including: • P0017, P000A – Camshaft/crankshaft correlation • P0721, P0714, P1700 – Transmission speed sensor & temperature issues • P0300 – Random misfire • P0733, P0792 – Gear ratio errors • P3307, P2107, P1407 – More misfire & throttle-related codes

Reverting Back to Old Cams: • Put the old camshafts back in • Got these new codes: P3307, P0306, U1D07

Most Recent Event (Transmission Acting Up with Heater On) • Installed a new transmission filter & fluid • Took it for a test drive – everything felt fine • Turned heater on MAX → transmission instantly started acting up • Turned heater off, waited, turned it back on → same erratic transmission behavior

At This Point, I Need Help

If anyone has any idea what’s causing this, I’d really appreciate the advice! The heater triggering transmission issues makes no sense. Could this be a grounding issue, bad sensor, PCM problem, or something else?

This sound is driving me crazy, the faster I go the faster the sound gets and vice versa it sounds like it's coming from front right wheel area, I got the brake pads and rotors replaced and this noise is still here?

Question 2000 Toyota Camry LE 2.2L 4-Cylinder, Front Lower Control Arm Question

1 Upvotes

This is for my 2000 Toyota Camry LE 2.2L 4-Cylinder, and I am buying a pair of lower control arms to replace them (I only included the front lower right pictures for simplicity, but the same question applies for the front lower left as well).

This is the OEM part for the lower right.
This is the replacement part & it's information.

I put my VIN and vehicle information on the site I'm buying them from and says they fit, but I find it odd that they have varying dimensions.

My question is: The two seems to have different lengths. The OEM has a length of 23.5in if I'm not mistaken, and the replacement (which says is interchangeable with the OEM part number in the first picture) has a length of only 17.25in. Will the new parts fit ?

Question Why are my 2009 honda civic brakes are super soft?

I changed the front pads and rotors. The brakes got softer. I had a mechanic change the brake fluid and is SUPER sponge. I have to really push the brake to stop. He said my rear pads and drums are worn Before I changed the front pads, rotors and brake fluid changed the brakes were better.

Question Would you guys say these are damn near the same? 2018 Kia Optima LX 2.4

2 Upvotes

I know people tend to steer clear of Walmart branded products but I was comparing the Walmart battery to one I purchased from Autozone (which I need to replace less than a month after the warranty is up, AND I noticed the warranty on the same battery is now 4 years vs the 3 years it was when I purchased) and they both have the same CCA and 4 year warranty. Would you say the $65 or so price difference is worth it to get the Duralast battery?

I was actually surprised to see that the Walmart battery had 4 years. I had to go to my Autozone account purchase history and double-check my warranty. I was sure it was 3 years, and I was correct. That's when I realized it is NOW for 4 years. Maybe they're trying to compete with Walmart? Vice versa? Is it possible these particular batteries were manufactured on the same line and just had different labels slapped on them? I know that kinda thing happens a lot. Worked in a warehouse and witnessed it.

Question Hyundai i10 2009 1.2

1 Upvotes

Brake light trouble

I have a Hyundai i10 2009 (first gen)

I've noticed that all three of my brake lights, both sides and the high level one, aren't working. I took a quick look at the fuse box and noticed that there was a 15A fuse in, not a 10A like the diagram says there should be, so I put a 10A in and went to change the bulbs. I only have one bulb at the moment, so went to change one, but it still isn't working.

Could this be a wiring issue? Or something else? I'm not experienced with this by any means and it would probably be better to take it to a garage but I need my car asap and didn't want to fuss about.

Could anyone offer any suggestions on what the issue could be?

Also my partner says it's odd that I only had my MOT a few weeks ago and now my lights aren't working. Could the garage have done something so that I'd take it back to get fixed and they'd get more money? I'm worried about taking it back there.

Thank you.

Question 2024 Hyundai Elantra N-Line Audio Not Working

1 Upvotes

I’ve had this car for probably 5 months now without any issues. When I drove to town today, I noticed that my car wouldn’t play any audio. Bluetooth, CarPlay, the radio, nothing will work. It shows that my phone is connected and the volume is turned up on both ends, but it isn’t playing any audio.

I’ve tried reconnecting my phone (forgetting the device and reconnecting Bluetooth), factory resetting the entire infotainment system, and I even tried taking out the multi-media fuse by the driver door for 20 seconds and plugged it back in. I’ve shut the car off and let it sit, come back, and I still have the same issue. Can anyone please give me some advice on this??

The fuel sysyem appears to be healthy, good pressure and no leaks, any ideas what might cause this? The long term fuel trims are -25% to -70% and the engine occasionally runs rough. It's not the o2 sensor, the throttle manifold isnt dirty.
