I know its late, and many won't see this, but I realized I started my auto career 10 years ago this month. In 10 years of auto repair a lot has changed. I figured someone here may enjoy it. I will likely never be an auto tech again thanks to my upcoming district manager position with Chrysler, but back in 03 I started helping my grandfather at his shop. Since I've worked in car lots, new car dealers, and independants. A lot changed in that stretch. A decade ago, I remember these things:

Timing adjustments being a normal thing (today distributors are ancient history)

14 and 15 inch tires being 90% of what I changed (Now 17 and up are dominant)

Doing plugs and wires well before 100k (don't even have wires to do any more)

Doing exhaust work weekly (stainless has been standard since about 2000)

Doing some GM V6 intake job every week (they fixed most of their issues when the 3800, 3.1, 3.4 and 4.3 were updated)

Doing body work to pass inspection (cars rarely rust out today)

Doing Blazer ball joints and cutting rivets to change them (Blazers need ball joints more than I need showers, and the OE joints are riveted in. I can't remember the last time I saw a Blazer with OE ball joints

Replacing fuel pumps weekly (for whatever reason, fuel pumps have finally gotten reliable)


Seeing carburetors on daily drivers

Doing R134a retrofits (most R12 cars are long gone, long retrofitted, or aren't worth a few hundred bucks to update)

Replacing rear drum brake components

Returning shoes as cores (virtually no one wants brake shoe cores back today since demand is so low)


Seeing riveted brake lining regularly

Using the Snap On brick to diagnose OBDI cars

Doing timing belts often

Thinking 91-96 Escorts and Blazers were 2/3's of my work

Doing clutches on normal cars and trucks (now 90% of clutch work seems to be on performance cars)


Replacing sealed beam headlamps more than once a year

Taillamps usually took a 1/4 turn to remove (3157 has replaced 1156/1157 in nearly all applications)

Using green antifreeze in almost everything (GM had godawful Dexcool in the newer cars)


Conventional 5W30 and 10W30 was the OE fill on everything

A lot of Ford E-vans running around in fleets still had kingpins

Dodge's big vans had screw in ball joints that failed regularly

Every Honda needed an upper rear control arm

U joints were a common repair

Grease fittings

I am sure there are others, but this stuff stood out. Its incredible how much has changed. Makes be feel a bit nostalgic/ a bit "get off my lawn" lol
