This might mean a 1/2 inch socket wrench with a really long handle - the longer the handle, the greater the power to loosen tough bolts, or tighten critical nuts/bolts like the axle retainer nut (175-225 foot ft lbs).

If you don't have a socket wrench with a long handle, you can achieve the same 'power' by putting a piece of pipe over the end of the wrench handle.

A spare piece of 1/2" or 3/4" galvanized Plumbing pipe works great. Electrical conduit doesn't have the same wall thickness and might tend to bend - but will do in pinch.

How do you release tension on belt 92 gmc truck?

There is a spring loaded belt tensioner with a pulley located below the alternator. You will need a 3/8 drive ratchet or breaker bar(breaker bar gives you more leverage). Insert the breaker bar into the square hole on tensioner and push down or counterclockwise and remove belt. If tensioner does not spring back spray it with lubricant and work it back and forth-they stick sometimes.


If a breaker bar is 2 feet long and you exert 125 pounds of force on the end of the handle approximately how many pounds of force are exerted at the drive head?

The force at the drive head would be around 62.5 pounds. This is because the force at the drive head is half of the force exerted at the end of the handle when using a breaker bar.

The panel and breaker have to be of the same manufacturer. This way the breaker will fit into the panel. If the panel has a push in bus bar, the breaker must also be the type to accept the bus bar. If the bus bars in the panel are of the bolt in type then the breaker also has to be a bolt in breaker.
