Hi, do these bearings bring any relevant advantage, like durability over the regular ones? I mean, do they solve the durability problem?

Guys,

I am surprised there are no ink on the 808E here...

Anyone noticed it has been released?

There is a thread started in the electric off-road section for the 808E already

In theory I think they should last longer. I ordered some 13x20s to use the next time I do maintenance.

I hope so... I've mounted the 2010 gearboxes, and in less than a gallon I went through 8 bearings and yesterday it blew me 2 crown gears at the rear...

I must say this time I got pretty upset with this sittuation... It's a shame, because the rest of the car is bulletproof!

I might get back to the old 2009 boxes and maybe it'll last a bit longer.

Check your rear CVD pin, if that pin has any slop, the rear bearings will wear out and blow up quicker.

My complete solution to the front/rear diff issues:

1. Replace the CVD pin every week (it may sound like a bit of an overkill, but any slop increases the chance of failure, for as cheap as they are, you might as well replace them). If you aren't going to do it once a week, 1-2 times a month is HIGHLY recommended. Once you replace, load that CVD up with Hudy graphite grease to reduce wear.

2. Take the seals off the bearing and pack them with grease. The Blue Hudy Bearing grease works well, but Mobile 1 works great too. On the inner bearing, leave the seal facing the inside of the diff case OFF to avoid it falling off and into your ring/pinion (too much Chassis flex causes the seal to occasionally fall off).

3. Find some shims (not sure what kind, I will post the size and manufacturer later tonight once I examine them a little bit more), place one in the diff case BEFORE you put the first bearing in and after you put the second bearing in. This pancakes the 2 bearings which keeps the grease in and reduces the bearing failures. The 3 pan head screws in the diff case will hold the top shim over top of the bearing which makes it impossible for it to fall out.

I have left mine in like this for 3 weeks and haven't had a single problem yet. If you check this pin frequently (twice a month or so), you shouldn't have any problems.

Hope this helps some of you solve your problems. This can be done to both the front and rear...

Believe me, I love my xray, but these things are really starting to hit my wallet, and making me start to thing about going to another brand, at least until a new version comes out, with all these problems solved... The original xb8 kept me going for 2 years almost without any spare parts. The transmission took none... I would just love to see the driveshafts to become anything close to the old ones...

The thing is... I don't want to leave my car, it's just a so much better ride than the others...

+1.. j-concepts illuzion for me too..best looking body imho and high enough to allow the use of high volume air filters.I like the cut out around the exhaust manifold as well so it doesn't burn/melt.

Your talking about the little black guides that bolt into the bottom of the centre diff mounts ? If you are, just remove them. I dremelled mine off so that I could keep the inserts in the bottom of the diff mounts just in case they bowed when nipped up without them. Probably safe to just remove them completly, but just being thorough at the time

This bearing issue is driving me crazy, to be on the safe side you have to change bearings before every race, i have never had more then about 2 hrs runtime on one set so now i am trying this mod.
2 pcs 355108 XT8 10t pinion
4 pcs 8x16 bearings
2 pcs 352001 diffbulkhead XB8ec (use the same front and rear)
1 pcs IF457 MP9 front axel
1 pcs IF458 MP9 rear axel for the 2010 chassis
