Default Jammin x1 x2 Question

I have a jammin x1 FT and on the rear hubs there is an awful lot of play. It seems like the bearings fit a little loose in the hubs which causes the driveshaft and wheel to wobble so bad the my camber probally varries about 4 degrees. My question is will the aluminum hubs fix this?? or is this just a poor quality thing and I should change the car instead? I have tried new hubs and same thing along with new camber arms.

4 just from the bearing? Are you sure you have the right size bearing, or it is a combination of the bearing and hinge pins, ect....? Something doesn't sound right to me.

Yeah, they sit very loose in the hub. Trust me I am no idiot and about 80% OF the play comes from there. And yes they are the correct 8x16 bearings

Sounds like the car has alot of wear on it, so replace bearings and hubs and camber links, the other thing to check are the balls because if the camber liks has alot of play with the balls then the dirt has worn them down and will be no good when changing camber links, they'll just wear fast again. Just changed mine and all is good.

Alum. hubs are just more durable but they will add weight to the car I just stick to the std uprights.

Get rid of the plastic uprights and go to alum. and you will get rid of 90% of your problem. I run the king headz alum. on all my Jammin's, and as far as weight go's, if you can tell the difference between the alum and plastic while driving then you should have a full blown sponsord ride.

Just know that the aluminum hubs are $60+... kind of hard to justify when you can get the plastic hubs, which includes upper arm end links, for 1/6th of that price. That's really why I never bothered to buy the aluminum rears for my old Jammin... six sets of plastic hubs are twice the lifespan of the car anyway... provided you're not bashing it.

x2. We're talking around 20 grams of difference here... when you're car probably picks up 100 grams in dirt alone from a dirty track.

I did replace the entire rear suspension,arms upright,camper links with new balls and new bearings. You can actually see the play where the bearing sits in the hub it wobble''s all around

Even if you do go to the aluminum hubs, you will end up with
the same slop after a few races. I went to great lenths to tighten
my Jammin truggys up so they had almost zero slop. I found out
that they handled better and were more consistent if you leave
some slop in the suspension. The ball links were always a joke,
even when you pop a new one together it has some slop.

get the aluminum, my jammin worked best with them and I cant rember them ever wearing out (make sure you use the setscrews to lock the hingpin, so it can wear the aluminum out). the only way it can wear the bearing hole out is if the bearing locks up or gets extreamly gritty. I think the bearings last longer as well cause it doesnt press in as hard as the plastics do.

Yeah thats what I was hoping that there was something to fix this. I didn't want to spend the money and have the same issue.
