If you look at the side of the differential housing you will find a plug fitting.The fitting looks similar to an allenhead bolt but it has a four sided hole that a 1/2 ratchet extension will fit into.Remove the plug insert your finger straight in the hole.If it has oil in it the level is ok.If you can't feel any oil you need to fill it to the level of the ...

I have similar symptoms when my sway bar bushings need lubrication. There's a distinct sensation at low speeds where dumps will cause relatively sedate deflections and rotations of the bars. The bushings will briefly bind, release, bind, release, etc. in fairly quick succession. It can sound like a pop - clunk if it's just once catch and release. This ...

The universal joints.If they are really bad you may be able to see signs of rust on them or if you are under the vehicle.You can also grip the drive shaft while the car is supported on jackstands and the rear tires off the ground and see if you can push/pull it and look for movement.If you twist the driveshaft by hand you may be able to feel the click in the ...

To tell you specific details, like when it should be changed, I'll need a specific model. "94-96 B-Body" covers a pretty good range (Impala, Impala SS, Caprice). I will warn you, though. Most cars (and trucks these days) don't have a plug built into the transmission pan to let the fluid drain, so you'll more than likely have to drop the pan anyway. Looking ...

I can't say for certain if it's bad. However, I would not let the transmission run dry while the pump is moving. If it's anything like the oil pump on a car engine, it will use it for lubrication of the valve bodies and hydraulic parts. It may get air in bad places as well. However, they do make automatic transmission transfusion machines that do almost ...

Cold water will not crack the block. The hose procedure is common and you just have to be sure that you add the correct amount of antifreeze and water (preferably demineralized) when you are finished flushing. Remember that automobiles in colder climates sometimes start when their coolant is below freezing. Granted both the engine and the coolant warm up ...

There are two methods I use.One is to attach a piece of hose to the pointed tip of the gear oil container and stick the other end in the differential.Then squeeze the bottle.The other method is to use a suction gun that looks like a big metal hypodermic syringe.You suck the oil in then push in the plunger and squirt the oil into the fill hole.

If it's a single click it may be the brakes. The self adjusters activate when the brakes are pressed when backing up, they are under spring tension and can make an audible clicking sound when they adjust. If the adjuster screw is seized the noise would be much louder as the adjuster rakes across the teeth of the screw.
