The rear differential on my Losi Night Crawler is getting pretty hot when I run it.

I did some googling and I see a lot of people around the net talking about "drilling a small hole in the diff, and adding grease, then sealing up the hole with a screw."

Is that really a good idea? Any other ideas on how I can solve this without doing minor surgery?

Yes the small hole for grease is the best way to solve the issue I used a small set screw to plug the hole and added grease every few hours of run time, and another issue you may be having is a incorrect shims on the worm gear. If you want any more info I'd check out rccrawler.com tons of tips and tricks under the team losi section.

i agree with sct a small hole in both front and rear diffs to put grease into is a good idea. when i had mine i had a hole on the back side of the front dif and a hole on the front side of the rear diff. i used a syringe style medicine dropper to put the grease into the axles. and like he said also go check out www.rccrawler.com lots of good tips and tricks there for the lnc.

I didn't like the idea of drilling a hole, so I didn't.

I just filled my diffs with Grim Racer Marine grease. Ran the LCC in a season of comps and GTGs for over a year. Opened up the diffs for maintenance and no grease was lost and all the original gears looked like new.

Another year goes by and the grease was still in there. I cleaned it out anyway for routine maintenance but I am very impressed with that grease. No sling, high temp and waterproof plus the tub cost $3.00 and will last a lifetime.

I sold the Losi and using MOAs now but I still miss the old rig.

Thanks for the replys and the info everyone. I really appreciate it.

I'm going to get some grease and get this taken care of tomorrow. I'll let you know how it does. Thanks again, Merry Christmas!
