Bought my first truck *1989 Peterbilt 379*

You have to pull the advance unit out of the front. It's not hard, but it's easy to screw up pump timing.

 

You may be better off to take it to a good tech and have the whole unit rebuilt.

 

Looks like I nead to buy some seals so I will
know that I have good ones and not something cracked or dried out.

 

Just a heads up: the carpet, passenger side front corner by the door under the heater, will be wet in the summer.

The only bad thing about that truck is the suspension. It rides rough by today's standards. Petes low air rides sooo much better. That is the only drawback to that truck. You did good, really really good.

 

Pix...?? Oh boy, here goes the dog chasing its tail again , LOL, sorry just had to!! Be safe out there.

 

LoLoL.. HIS actually showed up... then again, maybe until YOU did??? great....Houdini in WV.

 

Always checking on you my friend !

 

Yep. And a rather easy swap. Unless it's a show truck where keeping it completely original might matter, there is no reason anyone should suffer the back damage caused by that suspension.

 

always appreciate it, neighbor! Hop skip and a jump on '77, LoL~!
