Sign of grumpiness, cheapness. So cheap I didn't even go for a premium brand 4wd to emulate. Poor man's TL01B crawler #tl01b #budgetrccrawler #tamiya
first step was to clean all the old grease off the gears and chassis so I can replace the grease with a semi-dry lube that should cope much better with dust.
I also heard the gearboxes are prone to dust ingress, so I've cleaned out the whole chassis and RTV-ed all the gearbox seams 😵.
I also did the diff housings too so hopefully I can pack them with grease and get semi-limited slip action without grease leaking out everywhere.
