Default ST-RR maintenance?

Just wondering how often you guys change certain parts on your ST-RR. I have been putting allot of time on my truck and haven't really replaced anything that hasn't broke. I'm thinking I should put in new diff cups and bearings about now, but maybe I'm wrong? I got 10 or more race days on this truck, plus practice days.
Thanks

the strr is a very durable truggy.. as long as you are cleaning and inspecting the diffs and other parts you will be fine..

Personally, I go through and replace things as part of routine maintenance before they're broken ~ worse case scenario, I've got a used spare diff (rebuilt and clean) and other bits and pieces I can throw at the truck in an emergency or as needed to get through a weekend.
I have had the truck torn apart a few times, changed oils, etc. But the parts look OK. So you just randomly replace stuff?

Unless your rich I would not replace parts that are not worn just because..When my CVD's start getting slop, when bearings have to much play, excessive slop in suspension parts..I will change/replace then..Kyosho parts are not cheap and I dont have a huge RC budget, I do keep spares and I dont let stuff get excessively worn..I guess it's a judgement call..

This is kinda how I do it right now.

I think using rocket-mtrsprts method it would be cheaper to just buy a new truck and sell the old one. And I wrong? I mean i can get them for $600 new, I'm sure I can get $250-$300 for my used roller. I am thinking I am right.

Well I went ahead and did a complete tear down last night. To say I am impressed would be an understatement. These diff cups and gears all looked brand new after I cleaned them out. Not a single sign of notching!!!! Man my Losi buggy will notch the diff cups after 1 race day. This ST-RR has at least 10 race days, 4 of which had 30 minutes mains.

So all I did was give it fresh oil, nothing else looked in need of replacing or was sloppy with the exception of the rear hubs and a few bearings.

Yea..My ST-RR is the same..Very little wear, bearings showing signs of slop but not any more than any other truggy I've had.
