Auto Repair

I have a 2004 Trailblazer LS with the 4.2L I6 and this problem just recently started and I found this video on youtube of someone having the exact same problem. www.youtube.com/watch?v=ZxFkboGEKxk‎ This noise is only there in reverse and drive. If you put it in park or neutral it goes away. Also goes away if you give it some throttle while in gear.

Looking at dropping the pan and doing the 8 quart swap this weekend. Is Valvoline Max Life Multi-Vehicle ATF at $4.50/qt as good as Advance Auto Dexron IV at $6.99/qt? It says recommended by valvoline for GM Dexron II/III and IV. Would hate to pick the wrong product...

We have a 2005 Chrysler Sebring Touring convertible that was recently towed for an insurance claim. The vehicle was involved in an accident in which it spun around on the freeway and struck the median wall with the left-hand side of the front bumper. The airbags deployed and cracked the windshield on the passenger's side, and the bumper was damaged, as well as the left headlight, tire, and the battery. The left wheel is no longer aligned and scrapes the wheel well when in motion. After being towed to an auction place and assessed, the insurance company stated that the damages to the vehicle exceeded what they believed the vehicle was currently worth, and deemed it a complete loss. In the end, it was decided we would opt to keep the car and do the repairs ourselves, and the insurance simply mailed a check to us for the assessed value. They towed the car back to us. However, when the car was taken in for an alignment, the service was withheld because there is apparently damage to the rear ball joint, the lateral links, and the upper control and lateral arms. The towing company caused additional damage to the bumper during the towing, but as the bumper needs to be replaced anyway we deemed that alright. However, was all of this damage to the rear suspension a result of the accident also, or was it caused by being hauled up by the front end and pulled 60 miles? Or could something else have happened to the vehicle during that time away that may have caused this?

I have read tons of threads detailing the same problems I have… Cars turns off while driving and may or may not start. The voltage fluctuates and dims the lights and such. Now it wont start. The battery is good. The alternator is good. I put a new computer in it. I don't know what else to do. I've seen lots of suggestions and no solutions. On top of this awesomeness, I found this relay/sensor that seems to go nowhere (picture below). There is also a second something or another that you can see in the bottom right quarter (red wire grey attachment underneath cruise control module next to that bundle of wires) that seems to go nowhere. I didn't unplug these. Any help would be great because no one ever seems to fix this problem…or at least report how they fixed it.

Hi, I have read all the threads I can find, watched a number of youtube video's, and read on other forums how to replace the hinge pins on my 1999 Sonoma. My bushings are shot, the door sags, I can hardly close it. Instead of clips that hold the pins in, there seems to be a glob of weld on each side where the clip should be. It is bigger in diameter than the hole where the pins go through, so I am afraid to pound on the pin. I tried to knock it off with a hammer and chisel, no luck. Has anyone ran into this problem? I don't have a chop saw and my sabre saw wont fit in there. Thanks

Quick question for you guys, please let me know if you have this kit, poll attached I have this kit also, because it was cheap but disappointed in the poor quality problems, and so I've been working on it, to fix all the poor parts & scratch building new front+rear end, wheels+tires, and other detailing bits to make it look nice & right! Why? I'm considering making into an affordable trans-kit LMK Thanks! :smokin: Attached Images 5452998_1_l.jpg (45.7 KB)

I just replaced the factory water pump on my '02 Venture van, at 94000 miles because it was leaking. I installed a new pump, Napa (Gates) #41020 ($30 here in Canada). It's working and not leaking, but after running about 2 minutes, it starts to make a "buzzing" noise, not too loud, but doesn't sound right to me. Are there any conditions other than defective bearing that could cause this? I torqued the bolts to the spec 89 in-lbs (7ft-lbs) in 1/4 turn increments and used Permetex "Water Pump RTV Gasket Maker". The new pump has a stamped impeller, the factory pump had a cast impeller. Is the new Gates pump poor quality? i.e. should I have gone with the GM pump? Thanks.

Replace compressor beginning of last summer and all worked well. Now if i start truck from cold start ac will work, but if i stop or turn off truck the ac will not work. I can go 5- 10 miles down road and ac will start working agian, anyone have any ideas? Compressor is not engaging during this time. I can jump across pressure switch and compressor will start. its an 03 gmc sonoma crew cab with 93000 plus miles with 4.3
