That looks like a lot of work - which is unfortunate for me as my UDR needs a full service… 😞

@DownShiftDrew 8 месяцев назад

2years later and I’m still coming back to this video as guidance!! I just had to remove my transmission and you helped me. Thank you so much.

@TeamRC3D 8 месяцев назад

Glad it helped!

What is the part number of the tiny bearings

@TeamRC3D Год назад

It’s in the exploded diagrams

That's a great video. I've just ordered my Fox version, with the open diff parts. There's no really loose surfaces near me. Subbed! 👌

Many thanks - you will love it

There's nowhere near enough grease in that axle housing.

Would love more UDR maintenance videos

We have done a full nut and bolt rebuild on one

Hello I've got the same bearing literally exploded and i have to replace everything just like you did

@TeamRC3D 7 месяцев назад

Yes it is one of the first things that fails

@mcollins863mc 8 месяцев назад

I just replaced the pinion and spur gear as they had missing teeth and now the rear tires aren’t spinning as fast as the front, did replace the center drive shaft from front as well, any ideas?

@TeamRC3D 8 месяцев назад

Check the planetary gear system

@ryano8613 3 года назад

I literally o-ring the outters and pinion output, drill a hole and thread a micro grease zerk into the planet and diff to be able to grease it. 50hrs hard driving and no issue yet. Good on you for taking the time to share this. Thanks!

@ryano8613 3 года назад

Better add, also added zerks to center trans in 2 spots, and top of front diff cover and right stuff seal flanges and o-rings on all outputs. Also added traxxas blue silicon CV boots to ALL cv points. Remember folks, it's the heat that breaks stuff, these planetary systems spin hot and fast. Don't over run the car. Give it cool downs.

@TeamRC3D 3 года назад

Like that idea have you got any pictures of what you have done?

@Angelo-ib8ho Год назад

Got the same problem on my udr... the head of the screw is snapped off

@TeamRC3D Год назад

Depending on where it is sometime you can cut a slot or have to drill out

@codybib7829 11 месяцев назад

Can you please to the front one. If its already there, link please. Ty😊

@TeamRC3D 11 месяцев назад

The process for rebuilding will be the same once you have got the assembly out

@jessejames2546 2 года назад

How’d you get the 8 tiny bearings out of those two plastic halves? Got a bearing kit but couldn’t get those 8 tiny bearings out. I noticed if you tighten the pumpkin halves together to tight the rear axle will not turn as freely.

@warmfreeze 2 года назад

sounds like your axle warped from heat.. happened to me.. had to buy a whole new rear axle.

@jessejames2546 2 года назад

@@warmfreeze right on, it’s definitely seen better days

@rceverywhere4836 2 года назад

How often should you rebuild these?,

@TeamRC3D 2 года назад

Depends on how much use and abuse the truck gets and what conditions you run it in. When it starts to sound a little noisy or gears feel notchy we would take a look.
