jleamont Report post Posted May 2, 2020 Probably not for most to tackle on their own. Tight work space but otherwise fairly easy for the front. Haven’t started the rear yet... Share this post Link to post Share on other sites
jleamont Report post Posted May 2, 2020 I called it quits for the day with wrapping up the front. The rear looks like I might have to pull the wheels to conquer. It took about an hour per airbag to replace. Share this post Link to post Share on other sites
wildebill308 Report post Posted May 2, 2020 Did you have any leaks? How many bags do you have 8? Bill Share this post Link to post Share on other sites
jleamont Report post Posted May 2, 2020 Bill no leaks but they were deteriorated from age and getting hit with road debris. The rears don’t look 1/2 as bad but I will replace them also. 8 Airbags Share this post Link to post Share on other sites
f433921 Report post Posted May 2, 2020 Joe, Are side panels around the wheels hinged? Did you remove front wheels to provide better access? My coach is about the same age as your, what you see doesn't look bad, it's the part't that I cant see is what worries me. Jim Share this post Link to post Share on other sites
kaypsmith Report post Posted May 2, 2020 Joe, I went through the same actions last year, I replaced all 8 and it is almost a must to pull the rears, both drive and tag axel. Some of my bolts were so rusty that I used a smoke wrench to remove them. Hope yours are easier. By the way, I replaced all 8 shocks at the same time.

You have to brace the H-frame to the Semi Monocoque frame above it, lower the suspension unhook there air lines to the bags. Access was a bit tricky, most work was done reaching around the tire but some was done underneath sitting and swinging a ratchet wrench blind. if the wheels were off it would be easier but the risk dramatically increases. Being our driveway is asphalt I don’t trust stands to hold all of that weight. Share this post Link to post Share on other sites
wildebill308 Report post Posted May 3, 2020 Preventive maintenance = a good thing. How about some plywood pads under the jack stands? It would be easier on my RV if the wheels were off. I may change the shocks next year and will probably have someone pull the tiers off. Share this post Link to post Share on other sites

Herman Funny, when I was done I thought to myself wonder how old the bags are in Herman’s coach 2 hours ago, F433921 said: Did you remove the wheels? Jim Just the outer rear duals, installed 5 lug nuts just Incase my jack stand sunk and tried to dump the coach. Share this post Link to post Share on other sites
jleamont Report post Posted May 6, 2020 Follow up, 3 days has passed and the coach hasn't sagged, still holding is position from Sunday. Time to write this one off in the books as a success! Share this post Link to post Share on other sites
manholt Report post Posted May 6, 2020 As usual, job well done! Mine are good, but I'm going to have shocks look at...too much lean on tight corners. My AC was on the Spartan K-2, nothing moved in coach while traveling. This is the K-3 chassis and everything moves! Share this post Link to post Share on other sites

They still had a lot of resistance (no fun to collapse for installation). I manually compressed each on on the ground, they extended rapidly once I took my weight off of them and they were smooth. I put them all back on! Share this post Link to post Share on other sites
