We unhook the ride height valve and use it to raise the coach on one side as high as it will go,we cut a 4X4'' board to about 8'' long and wedge it between the axle and frame,then release the air out of the bags,the board holds the coach up while we remove the old bags.
Glen and I trade off on the bolts,he can get in places i can't,so he gets those,and I try to do my part.
Glen is good,without him I would not do that job.

Caging " T " bolts are used to cage the rear park brake air springs,
This is necessary to safely release the park brake for towing.

Another Randy Tip , that I learned.

The rear brake canister have a caging " T " bolt, washer & nut attached to the housing. They collect dirt, rust and are difficult to remove, Since the canisters are turned 180* left or right one of the caging bolts is impossible to remove.
So pick up a pair of caging bolts, from old canisters or keep the new caging bolts in your tool box. Tow truck operators keep a set in their trucks for this purpose. It is quick and easy to cage these springs, when the " T " bolts are in hand. Have a full understanding of Spring Brakes , they can hurt Ya.

I purchased Firestone 8997, these worked great for the front.
Others have used 8992, apparently the stud is longer or shorter ???
BB listed the 8997, Ridewell listed 8992, in the BlueBox for the front.
Rear air bags are Firestone 9039

Are these part numbers good for a 88 PT?
