Yes. Bushings are not serviceable on the TRE.
If you are going to use your new TRE in dry locations, you can probably get by for a couple years before you should consider greasing the wheel bearings. That's what I did on mine. I'd lube the boots on the radius rods as well with the teflon rec's listed.
Bought this tool. LINKY
for my wheel bearings
This year, with the record amount of snow and run-off in CO, my TRE was more of a Trails & Rivers Edition. I was in lots of deep water for extended periods of time. Try driving UP a river in 2 feet of water for a few miles. I made it. The 2019 Turbo-S, two other XP1000's and 2 more 900's could not.
I was re-greasing my wheel bearings (second time since so much water).
Have to disconnect the radius rods & front A-arms to pivot the hub to get the grease tool in. My radius rod bolt(s) broke second time around torquing them to 100 foot pounds.
When you grease your wheel bearings for the first time, pull the axles as well. Put some anti seize, spline grease, water proof grease, etc. on the axle splines. I had some left over Honda Moly60 spline grease. Specially made for splines. That's what I put on my axle splines.
You will love the TRE! It goes places others won't even attempt.
