Instinct28 Posted April 25, 2022 Share Posted April 25, 2022 My fj-09 has high speed wobble so when I get around to installing the Adrienne cartridges I'm doing new bearings in the triple tree but this schematic doesn't show the bottom section. I need to order both top and bottom right? Link to comment Share on other sites More sharing options...
Premium Member 2and3cylinders Posted April 25, 2022 Premium Member Share Posted April 25, 2022 A high speed "wobble" is not necessary caused by bad steering head bearings. There could be several possibly interrelated causes. You should perform a couple of simple checks (I think related in the shop manual) before going to the time and expense of replacing the upper (1) and lower (40, shown in the Fork diagram) bearings always along with their races if dimpled and/or worn). Which, BTW, are much less expensive at PartShark located in Indianapolis). Some people like the feel of the OEM type caged roller bearings versus the slightly more dull feel but more durable tapered needle bearing and race sets available from ie AllsBalls. I have 50k+ miles on my 15 and the SH bearings are still servicable; although greasing them would be good practice. I however do not pull wheelies, and likely couldn't if I tried. 1 Link to comment Share on other sites More sharing options...

If you haven't pulled several inadvertent wheelies without even trying, then I'm afraid something is bad wrong with your FJ. Or maybe it just took me a little time to acclimate my right hand... Anyway, yes, great info on the bearings. Partshark is a great source if you want OEM, and Online Cycle Parts (located just north of Indy; Partshark is on the northeast side) is another. There are several dealerships scattered around selling parts online at a discount. https://www.onlinecycleparts.com Personally, I'll be dropping in a set of All Balls tapered bearings when that time comes.

Premium Member 2and3cylinders Posted April 25, 2022 Premium Member Share Posted April 25, 2022 With my excessive mass, Givi case guards with DL and hiway pegs, larger screen, farkles, cell, GPS, RD, KTM handguards, ECU flash smoothing response, K-Tech Razor R lengthened and massaged fork, the natural tendency to wheelie is significantly suppressed. Anyway, I'm too old to try anymore. 1 Link to comment Share on other sites More sharing options...

I have pulled wheelies not trying but I'm trying to keep some tread in the middle of my back tire so I try not to. 😁 Link to comment Share on other sites More sharing options...
koth442 Posted April 26, 2022 Share Posted April 26, 2022 Just to get the silly stuff out of the way... check tire pressure(s) and rear wheel alignment? 1 '15 FJ09 Link to comment Share on other sites More sharing options...
