I don't like using a bumper jack

Mike the only problem with an axle type jack is that on some cars you are not going to be able to get the body up to get the tire out. My 67 is that way. Sometimes I use a combo under the axle, and the bumper jack to get the body up

Here's a TRUE story about bumper jacks

From 70-74, I was stationed at N.A.S. Miramar (now MCAS) and part of that time had a part time job at the station auto hobby shop

Sailors used to manage to do all kinds of silly, stupid, and sometimes dangerous stuff, but this was the worst I saw

One afternoon I wandered out into the lot, and here was a sailor working under his 57 Chev. He had TWO bumper jacks under the front bumper, jammed up against those big "tits" on the front bumper, without a jack stand or blocking in sight!!!!

I ran over there, grabbed him by the ankles, and ripped him out from under that car. He was PISSED, and wanted to fight. I told him to "think again." Under these civvies, I said, stands an E-5, and you "ain't" and I'm in VERY good standing with my boss here. I told him he could either go to the tool room and check out some jack stands, or leave and not come back.

He made the correct choice.
