#3339 of 3449 Re: Front axle won't engage on 4wd. [impalacab] by adamg70 Feb 20, 2009 (4:35 am)
Replying to: impalacab (Oct 01, 2008 10:03 pm) YOUR PROBABLY CORRECT,THE PROBLEM IS IN THE FRONT DIFF. LIFT THE VEHICLE,REMOVE THE HOUSING ON THE PASS. SIDE OF THE DIFF HOUSING WHERE THE SHIFT CABLE FROM THE VACUUM ACCUATOR IS ATTACHED. PULL IT OFF ABOUT ONE IINCH AND DETACH THE SHIFT CABLE FROM THE SHIFT FORK. NOW,WITH YOUR HAND, PULL THE SHIFT FORK OUT AS FAR AS YOU CAN. WHILE DOING THIS TURN THE FRONT DRIVE SHAFT[MAKE SURE THE VEHICLE IS IN 2WD SO TRANSFER CASE IS NOT ENGAGED] AND SEE IF THE FRONT PASS WHEEL TURNS. IF IT DOES TURN TOUR SHIFT CABLE COULD BE BAD ALONG WITH THE POSSIBILITY OF A WEAK DIAPHRAM IN THE ACCUATOR ITSELF. IF YOU GET A WEAK TURN OR A RATCHETTING SOUND IT PROBABLY IS ONE OF THE FOLLOWING. BAD SNAP RING THAT HOLDS ACCUATING GEAR IN PLACE--BAD OR WORN GEAR--BAD OR WORN THRUST WASHERS. COST TO PURCHASE PARTS TO REPLACE ALL IS AROUND $300 FROM A CHEVY DEALER. HOPE THIS HELPS. I AM A NEW MEMBER OR I WOULD OF ANSWERED A LOT SOONER. Replies to this message: impalacab (Feb 20, 2009 5:32 am)

Replying to: adamg70 (Feb 20, 2009 4:35 am) Hi, thanks for your answer. I've suspected that it would be something like that, but I was hoping to get it confirmed before I disassemblied it, so your answer is appreciated. I have bought a new actuator just in case, but the old one seems to pull real hard. I have lifted the vehicle, started, put it in D, in 2HI, 4HI, and 4LO, but I can't hear any abnormal sounds in the front axle. I will remove the housing as soon as it gets a little warmer here. It will probably cost a bit more than $300 if there's some other problem in the gear, I live in Sweden . Thanks.

#3344 of 3449 Fuel Pump Problems by s10mojo Mar 02, 2009 (9:17 pm)
Hi this is my first time here. I had a simple question. I have chance to buy a 1993 s10 Blazer 4x4. It only has 63000 miles on it. I was told it has fuel problems or bad fuel pump. Is there any major costly repairs involving full system in the 93s? Is there easy test to determine if its pump. Before i buy it. I figured for 700 bucks i cant loose either way. The main reason i was buying it was for parts for my 91 s10 that was in a wreck. But i may keep the 93. Thanks this is a real cool sight.Have A good night all.

#3345 of 3449 turn signal unit replacement by auto9999 Mar 03, 2009 (7:40 am)
I am thinking of replacing the front turn signal units. My body shop installed the ones without fog lamps for my 2000 Blazer 4WD trailblazer trim. My vehicle was originally equipped with the fog lamps.   Do you have to remove the bumber, or can you replace them from under the vehicle?

Replying to: s10mojo (Mar 02, 2009 9:17 pm) Well, the fuel pump is inside the fuel tank. Quick way to tell if it is totally dead is to turn the key to on, not start, and see if you hear a buzz/hum come from the gas tank. This will tell you if it is getting power. Then, a pressure test will tell you if the pump is working to spec. Any shop should be able to check this for you. If those are both good, there could be a problem in the "spider" that feeds the fuel injection. At this point, you are probably approaching the purchase price, but if this vehicle is in otherwise good shape, with 63K miles on it, there are still a lot of valuable parts to work with! Salvage parts have gotten very pricey, so weigh your alternatives.

Replying to: auto9999 (Mar 03, 2009 7:40 am) I am a bit confused with your question. To change the turnsignal bulbs, the grill snaps off and you can access both sides. If you are talking fog/driving lights, they are accessable from underneath. Replies to this message: auto9999 (Mar 08, 2009 7:52 pm) jlflemmons (Mar 09, 2009 4:58 pm) auto9999 (Mar 11, 2009 6:35 pm)

Replying to: jlflemmons (Mar 04, 2009 7:20 am) Hi jlflemmons,   Thank you for your message.   I am thinking of taking out the entire turn signal assembly - about 1.5 feet wide, a few inches tall, a few inches deep - with the orange plastic front plate equipped with the turn signal only. Then I would install a replacement assembly with both the turn light and the fog lamp.   image example: http://ketech-llc.amazonwebstore.com/shared/viewProductImage.html?http://ecx.ima- - - ges-amazon.com/images/I/41X6Z1Jxc-L.jpg   The assembly seems to be being fixed to the bumper unit by screws but I do not see the screws from in the engine room or from under the bumper.   The body shop knowingly installed the wrong assemblies - he said that he found a used set of parts without the fog lamp at a discount price. I benefited from the pricing, so I felt I would not ask the body shop to redo the job.   I would appreciate if you could tell me how to remove the turn signal assembly.
