Question Which Koni shocks for rear axles - 2017 Newmar Ventana FL chassis?

Strange wear pattern on one tag axle tire

Airing up tires today as we head into cooler temps and noticed a strange wear pattern on the driver's side tag axle tire. All other tires look fine. Any ideas as to what's going on here? Chassis service at end of this trip, I'll be asking Freightliner Custom Chassis.

I recommend the full alignment for tire wear. If the tag tires were cupping, that indicates weak shocks.

That's very close to what mine looked like before alignment. The local truck shop may also do the change out of the shocks and the alignment check for you. I'd definitely address it before you head out this summer.

I'll ask the truck shop I use (Excel Truck Group) if they can do the alignment otherwise FL Gaffney next visit will be one. Send cans please.

 

[Texas Clodhopper]

Send cans? She may say no.

I replaced the front soon after getting Active Air which was probably unnecessary and a reaction to something I felt was going on which is just normal RV driving. I don't feel any issues at this time on the rear shocks but the terrible wear pattern on the tag tires some think is related to shocks. I don't know. So I am only replacing rear two axle shocks and leaving fronts alone.

Checking part numbers...

Do you recall the front? I am concerned my rear air bags have a leak...if I pull the wheels off to re I kace air bags...I won't miss the opportunity to replace the shocks. While I'm up to my elbows in grease and road dirt.

Shockwarehouse should be able to tell you based on VIN I believe, or year/coach. I can't find the order for the fronts, only the rear two axles.

Thanks… I will send them the VIN…trying to get my ducks in a row before climbing underneath to listen for air leaks on the bags. Big trip coming up…still have all my annual maintenance to do…. Hopefully, resolving the headlight issue today when the diodes arrive.

There have been reports on shortages of air bags so you may want to check availability before doing anything.

I just aired up and climbed under with an ultrasonic leak detector. All 6 seemed to be holding. I was going to knock out both jobs at once…but looks like it will just be a set of shocks….

I have been looking into a lot of aging parts…and It’s amazing how many parts for my 2016 are discontinued.

Try spraying them with soapy water for a second opinion. Mine leaked and were replaced around 2 years ago. I probably could have waited longer but went with it.

Good idea. I’ll do it when I get to zerk fittings. They bleed down…but slowly. Might be able to hold off till next fall when we return to home base.
