I finished installing my ball bearings last night ... now i've got a problem i noticed ... after making sure the car still runs, when i use slow speed with the car in my hands, i notice a couple of the wheels are a little wobbly .. not too much, just a little .. and looking at the driveshafts .. they were not rotating straight .. they were a little wobbly...

the part i had the most problem with when getting in to replace the bushings was taking off that driveshaft and the pin that it is attached too .. that might still be not connected all the way ...

any ideas?

Check to make sure that the belt tension adjustment is the same on each side of the diff housing. This is a common problem when you take the diff housing apart to install bearings. It happened to me the first time too and it was because the belt tensioners were misaligned.

where are the belt tensioners? Do you have a part number or where I could look? I'm still new to names of some parts ... but i've pretty much taken my whole car apart and put it back together ..

the axle pins seem to roll straight .. but the wheels are still wobbly .. and i don't know why ...

The belt tensioner are the black round cams that house the bearings were the the drive output yokes come threw the transmission halfs. Each cam has a notch that it fits into buy using different notches you can tighten or losen the belts. As for the wheels if they are wobbly use traxxas black teflon washers to shim up the axles to tighten up the wheels.

ok, this is really starting to tick me off! ... i've been working on this car for over a week now and am still having problems getting the wheels to roll straight and not wobbly ..

basically I'm working on the front wheels now ...

i've checked to make sure the belt tensioners are aligned .. which they are ... now i've shimmed up the axles to the point where the axle pin is right against the bearing, before I did notice that there was a little additional space which was making the wheel wobble more .. now it still does wobble a little ...

my question is:
what else could be making the wheel wobbly? .. i put the teflon washers on the output yokes on the outside of each belt tensioner ..basically where the exploded view of the transmission assembly showed me to put them. i had to put 4 washers there.

i took apart the output yokes to do this, but i did put them together correctly and they they are solid and not wobbly themselves ..

where else can I look?

thanks,

Man, I would be getting ticked off too, are using the stock rims that the 4-tec came with, If you changed the rims you might half to use different wheel hubs, if you didnt change rims make sure those wheel hubs arent worn or something is jammed in between the wheel hub and the rim. And dont laugh at this one but are the tires glued on good, if there not when they spin it may look like the rim is wobbling..... I hope this helps you!!!!!!

no I'm using brand new rims ... I forgot the manufacturer name but they are full chrome rims .. it's the wheel itself that's wobbly, because i've taken off the slicks and it's still wobbly .. i got the wheel adapters for aftermarket wheels too and checked that .. that didn't make a difference ... and it isn't a problem with the wheel itself because when I put my old wheel's on it does the same thing .. i originally thought that the old wheels were out of round so I bought new ones .. but that isn't the problem ...

arrg! i havn't had a chance to try anything else since i made this original post ..

thanks,
