I wanted to change my 33 year old air bags. I finally attacked the
job. Here is the first one:
I have a new set of air bags on order. The job was not too bad.
The bottom bolt was not seized, it seemed to have anti-seize compound
on the threads.
The bolts on the top were difficult to get to but there is enough room
to get a socket and a breaker bar in there. With lots of pulling and
tugging I got them out. They are 9/16 inch bolts which is good to
know since you can't see them.
Mine were rusty and a 9/16 12 point socket slipped on them. They
were rusted a little smaller. I could get a 14MM 6 point socket on
them and then I could break them loose.
I think that while the air bags are out I will replace the air lines.
I have heard that some of the modern industrial push on plastic
lines work well. Anyone have any suggestions?
While I am at it I may install a pressure gauge to measure the
air bag pressure. I always like to know what is going on with
While I was in there I pulled my tag axle brake drum:
Clearly the electric brakes have problems.
