I recently lost the radio in my every day Saab. I went to crutchfield.com to look at a replacement stereo. I wanted something inexpensive that would simply replace the radio in my car. I was surprised to see the many options and reasonable prices.

For less than 200 dollars, I can fit a replacement radio, with a CD/DVD player, Bluetooth, a video screen and a touchscreen. For a couple bucks more I can add a back up camera.

A unit with all of these features and GPS is roughly the same cost as a stand alone portable GPS unit. Of course, buying the unit from a place like Crutchfield includes plug and play wiring and all hardware needed to make the installation look factory original.

I am amazed at how many features these aftermarket stereos have, and at how much the cost has come down. Now, if I can figure out how to add side curtain air bags, collision avoidance and adaptive cruise control I would never need to buy a new car again.

EASY OIL SEAL INSTALLATION TOOL

Anyone who has replaced oil seals without removing the shaft that seals against the seal knows what a struggle the seal installation is. Think of replacing the front main crankshaft seal in place without removing the timing cover or the crank shaft. This job requires applying equal pressure around the circumference of the seal, or it will warp or bend.I have taken several pieces of scrap PVC Schedule 40 drain pipe and cut it in lengths of three inches or so. Interestingly, the diameter of many grease seals is the same diameter of PVC drain pipe. The thickness of the PVC pipe is the perfect thickness to use as an oil seal installation tool.

I have diameters of inch, inch and a half, two inches, two and a half inches, three inch, etc., sitting on my tool shelf, standing in the ready to use for seal installation.By placing the appropriate diameter pipe over the seal the seal can be easily tapped in to place with a mallet. For larger diameter seals, and pipe installation tools, I have a piece of 2 by 4 to place over the pipe before tapping with a hammer.
