cobra boat trailer need help

[alexr1905]

i have a 91 bayliner cobra bass boat and matching trailer i got done at the lake one day and noticed my tires kick in at the top and out at the bottom ive done some reading online and that seems to be the normal but the passanger side tire kicks in a lot more at the top then the drivers it also moves up and down if i spin the tire by hand i checked bearings they seem good ive checked spindle and that seems good the inside of the hub seems to have some grooving on one side but not the other side(between the two bearings) please let me know of anything to look for im 45 minutes from a boat shop and dont know if it would make the drive

If the spindle, hub and bearings are in good shape and tightly mounted to the frame than I'd look at the condition of the axle itself and the rest of the trailer to make sure there is no unseen damage compromising it's rigidity.

The bearings can look "good", but might be worn. is there any side to side movement with the trailer jacked up?

i just replaced the bearings and race's the outside race was loose but it still is dished out at the top i guess im manly concerned on the ability to tow the trailer the spindles welded tight and the axles still bolted to the springs ill try to upload some pics to show you

Re: cobra boat trailer need help

Could be your axel lost it's spring. Do you have a solid bar axel or steel tube axel? Take a look at snowmobile trailers, utility trailers, boat trailers etc with solid bar axels. When those trailers are unloaded the center of the axel will look like it's bent up and the tops of the tires might even be tilted out. Now load the trailer, the center of the axel will likely look almost straight and the tires will be straight up and down. Maybe your axel is getting tired.
Oh, if you free spin most tires they will look like they are going up and down some. No tire is a perfect circle. The main thing is that your rim IS a perfect circle.
