95 Thomas air brakes . Well the problem I had was that the W. W. Willams shop was under staffed (5 or 6 techs) and didn't know what they were doing "with my bus". 4 months go by they quoted a new diff +labor 4.2k
I asked for model# N190 4.44 Spicer diff and I ordered used 1 from Vander Haags.
3 Months later I had call to ✔️ on bus they said spindle is bad, $2k to ✂️ cut and weld new 1, 2 mnth wait on that servs
or new used housing N190 + matching axels ordered all from Vander Haags with same rep.
3 Mnths later I check ✔️ again and they say that they can't get the parts to fit together
and they are trying to figure it out. I call international they say bus originally had N175 4.44 rear
Now bus is at international shop
fingers crossed
WWW didn't charge me for anything
