Hey all, I'm going to be replacing my rear valve block for the air suspension. I've removed it before, for a rebuild, and unfortunately was missing an o-ring in the package. I reused the existing however the unit is still leaking. I've ordered a complete replacement this time because the process of removing and installing is a nightmare. I'm sure anyone that has done this can verify. My question is, does anyone have any tips or tricks for this procedure? Any special tools or methods? Ideally I would love to pull the body off, lol.. but seriously, if you do have a suggestion I'm all ears. The front and middle were a dream compared to the rear. Cheers!

 

I have done this - yeah not fun - but possible:
Drop the spare tire, have patience, and wish you had smaller hands! (or find someone who does to help)

BUT

Since you are replacing with new, you will get to push-fit the lines into the voss fittings (new blocks come with new fittings) instead of threading the old ones on in place
So that will be a huge bonus this time around

 

Thanks for the response! I think you made my day reminding me that I'll get to push the lines into the new fittings . Screwing the lines in last time was the hardest part, removal wasn't terrible.

Interesting note about dropping the spare. Does this allow you do reach in from the opposite side? I hadn't considered this when rebuilding it last time. I've never dropped the spare so this might be a good opportunity to make sure everything works properly.

 

Trying to remember now - it's been a while and I forget - I just remember doing it haha
It's possible the only advantage to dropping the spare was extra light allowed into the valve block area

Regardless, if you've never dropped yours, this is a good time - much better than testing on the side of the road!
Then you can see for yourself if there are other advantages that help valve block removal
