Axle damage - is this normal?

[killerkip]

I have had a pajero metaltop for years, and the reason I don't run it anymore is the damage to the central axle (after 50 packs or so). Now recently I bought a juggernaut2, and after about 10 packs, this is what the axles look like. I think this is extremely fast to have such bad wear. Is this normal or am I just very unlucky - axlewise?

I believe that those axles are a weak link in the Jugg2. People have adapted Traxxas sliding axles to fit. They are much cheaper to replace. Check out RCMT. I believe the details on the conversion are there.

Hi, thanks for the advice, but I cannot get on to RCMT. I tried, but couldn't. Any forum that's that hard to get into is not worth getting into...

So I won't check it out, but will see if I can find traxxas axles...

Yeah, those definately look worn out, after 10 runs that's not really good! []

I think, becasue it has quite big tires too, that there is a tremendous torsion force put on the axles wearing them out rapidly because of friction... []

most of this damage happened in just 2 rock crawling runs... unfortunately...

If you like RC monster trucks then RCMT *is* worth the silly amount of headache to join.

The Juggy forum there has more than 8000 posts and is the most popular. There are a large number of good resources (people) there whom really know their stuff about RC monsters.

Every XC based chassis I have seen hasn't had this much wear in it. I 'think' these couplings are the same as the 3 speed series but in a different material. I have been experimenting with some heavy duty plastic UJ's will post the results when I manage to break one. They are designed for IC boats so can handle plenty of torque.

Did you get a wheel locked and try to tear your way out of it??

Looks bad to me, I have seen UJ's off 1:1 cars like this, but usually from a gross overload on the drivetrain.

Those UJs do need greasing, if you run them

dry & through dirt what do you expect?

Some of the RCMT folk do stuff them full of grease

and then wrap them in a long balloon or some

silicone shealth (made for offroad shockies?).

*laugsh* Just like 1:1 cars really. The rubber 'sock' idea sounds the best. It's just a sad side effect of the places we run the cars. The drive cups in most cars cop it from the dog-bones and universals are no different..

[WillyChang]

Ahh yes... those good old days of crawling under and pumping

the RWD's tailshaft UJ nipples with the ol' greasegun.

.... hang on, that was only Last Month!!! []

CVDs on the 1:1 FWD will also wear amazingly quickly once the

rubber boot perishes and the joint loses all its grease

and grit gets in - could become junk in under 1000kms.

But if you catch it early enough, not many ppl know its

possible to clean it up, regrease and renew the rubber boot

and it'll keep working on happily... at the fraction of

the cost of a new or reconditioned part.

Exactly...

I wanted to sock the joint (ow this sounds like a reggea song [] )but did not think there would be enough room between the joint and the gearcase... That's why I didn't.

First thing I'm gonna do is clean and grease them... And put a sock around...
