Out of curiosity, with the D52-8 being the same axle as the 6000 and 7000 why did you change? Comfort or was it recommended? Also, what's a wet bolt? Is that the never lube bearing?

You will want to verify this for yourself but the three axles are not the same. Yes they look the same and they each accept the same brakes and mounting gear. But the thickness of the internal axle walls increase as the rating goes up. I used to have the numbers but where they are now is anybody's guess. Too many of us were bending the D52 axles. I went to the 7K axles which has the thickest walls to minimize the chance of bending.
Wet bolts are now standard on Montanas (and most other upscale RVs). They are the pieces that attach the spring ends to the shackles. In 2005 you got a threaded bolt with a plastic bushing and thin material shackle plates. Wet bolts are drilled to allow grease through it and out to the bronze bushings, There is a zerk fitting on each bolt which is used to lubricate the assembly. The shackle plates are twice as thick.
The plastic bushings wore out easily and allowed the bolt to wear through the holes in the shackle plates. There was lots of discussion here on the MOC about this problem.
