Wheel Bearings
Why do the newer cars and trucks never have to have the wheel bearings repacked but rv's still need them to be repacked. Plus why don't tt & 5 th wheel mfg. offer an odometer option on their wheel...

The new trucks have cassette sealed type bearings. At least my 06 Chevy does and I know the newer Dodges do too. Most have reported they have failures sooner than old regular packable bearings. I would not want them on my TT.
As far as packing trailers bearings. My TT is 28 year old and I remember packing them twice. Both times I was doing brakes so I just repacked them to make everything like new. I check them about every 7 years or so because that is when it seems I need new brake parts. During my checks I never found them in need of packing. Never. I put on about 4 to 5K a year on my TT.
I think most if not all new vehicles have unit or non serviceable cartridge type bearings. Whether they last as long as the previous serviceable bearings is debatable. There is a definite cost increase as most cannot or the SOP is to replace the entire assembly rather than replace the cartridge bearing.
