Great! Yep, I really do like that blue - I love the way it changes in the light.

All,

I need to know whether I need to Silicon Grease my TRX-4.
I recently bought the crawler new and want to know if there is some best practices I should be following.

Well this is my first trail rig so there might be other methods people can suggest but on all of my Traxxas vehicles I like to use marine grease in the bearings as well as to better seal the receiver box.

I was advised to grease the Diffs, is that required?

Of course, check all, the diffs and transmission.

Good method.

Any photos, what do Diffs look like and can I get to them without dismantling the defender?

duuude, that blue is looking great!... I really wish the wife would beg me to buy her a crawler. She loves blue. I'd buy this color for her in an instant!

Mate, you can took out the diffs covers in the TRX4, only a few screws (the screws are in the oposite of the cover), and the gears are visible, the transmission is slightly different, you need to disarm it.

What do the diffs look like, the grey bulk in the middle is the axle right?

I don’t want to sound rude but it’s much easier to see then explain. You should watch this video because it explains very thoroughly and it’s how I’m learning!

You're right mate, I'am just trying to avoid I don't stuff it up.

Your wife should talk to mine! She convinced me to buy the Yellow Edition, but she always wanted the Red (it matches our "real" cars!) - 2 weeks later we bought one!

I fell asleep after a few mins, the guy is just removing screws.
What did the diffs look like, he never even talked about it.

That was covered in the other link I posted re Diff Greasing, here: https://www.youtube.com/watch?v=9aq0IusoAf8&t=118s

He get's to the differentials themselves at 3:54. His in fact, are almost grease free, unlike mine that were nicely lubed.

So you know, here's the front diff, with the cover in place (yours are grey)



Here's the rear diff exposed:



Here's how they both looked inside, with what I consider to be plenty of grease:



The locking mechanism is on the left of the main, central bearing and should be grease free.

The "exploded" diagrams that came with the car (and are on line at Traxxas's Support page) give a good idea how the cars go together and, come apart!

But, I wouldn't worry too much about this stuff until you've used it in mud or water! And when you do, the front U/Js (CVs) are just as important, along with the portals. But as has been said, don't worry unduly yet! Plenty of accessorising to be done first!

haha we have 3 vehicles and they are all red as well! Maybe I'll show her the red defender again and maybe she'll change her mind lol. It'll match our 3 red real vehicles! I already have a red UDR, red defender will definitely fit! only one different will be the grey trx6

Thanks for the detailed explaination.
So the pumpkins are the diffs then ?
Are they also referred as the Axles?
I took the defender in water yesterday but it was clear.
Does that count has having to grease the diffs.

Also what is the CV?

Excellent video mate.

[TITANIUM94010]

Wait quick question, are the central bearings supposed to be free of grease? I put some grease on mine yesterday, the diff locks work well as of now.

I think a little of grease don't bring problems.

[Squeegie]

Although the crawler kit has a slightly longer wheel base then your Defender, it is basically the same underneath.

You really should go through the assembly manual to familiarize yourself with your rig:

Have fun!

I read through the whole manual and now I have a better understanding of what everything is, I will try and get some grease in the Diffs

That Blue body is fab - time to ditch the grey one - and sent it over to me!

I assume you taped the vent holes in the wheels?

I was not planning in water logging it, just happens to be that way on the day due to rains the previous night.
So the vents were not taped and therefore had to squeeze the water out when I got home.
As for the grey one, I use it on fun rides and blue one where it’s easy terrain.
But am just amazed at how the defender holds up or may be Iam getting better .

"Gravel Road"!? Blimey, I thought things were only bigger in the US, but that's more like a volcanic foothill than a gravel road. The Defender covers it well.

Agree, the Blue looks superb! But, I see an empty roof rack and no add-ons or stickers.

Dude, time to get "accessorising"!

Iam waiting for “accessories “ to arrive from Ali Express.
What do you use to fasten them to the roof rack?

[DerAlteFritz]

I use scale bungee cords. You can buy them in different sizes pre-made or get a kit to cut your own and add the metal hooks. I also have a custom made cargo box on top of my Defender. It has a magnet glued to the inside and I glued another magnet to the bottom of the solid part of the roof rack.

[deuter]

I might just use blue tac

I really like Reinhard's magnet system.

But we use a combination of things. Some "scale" rope to hold the travel trunks, thin elastic (that looks a bit like rope!) to hold things like the crate of Coke's and the tent on mine (the Yellow one), a bungy cord "net" for a few things on wife June's and a thin net (from Killer Body) for the smaller items on mine and, double-sided tape, the "spongy" type that allows a bit of leeway in surfaces. I have tried Blu-Tac or similar, but it doesn't like roll-overs!

A couple of the items came with fixing screws and they required drilling of the rack. Not sure I'd go that route again, too "permanent".

The Traxxas items come with screws (axe and spade) and I drilled side flat panels of the rack and the traction boards are held with cable ties....

I think cable ties and double sided spongy tape is what I will stick to, good idea.

Spongy tape works, but from experience, they get dirty really easily, especially if you run in dusty conditions and rollover.
