AISIN FHS-005 4WD Free Wheel (Locking) Hub - Compatible with Select Chevrolet Tracker; Geo Tracker; Pontiac Sunrunner; Suzuki Sidekick

I used the other reviewer's info on bolts, the old hub bolts are too long. Make sure you mark (white perm marker, etc.) where the top is in the free position and verify lockup works; I had to take the wheel off, install the base, and then install the top. Had to spin the top a few times to get it in the right notches since I forgot to mark the first hub. Using a wrench makes for a snugger fit (torque to spec) but a driver but will not fit (Allen wrench will) if the top is installed first. Quality product to replace my old OEM manual hubs, my Chevy Tracker 4wd now works.

This kit does not come with the bolts necessary to bolt it to your knuckle. It also lacks the bolts necessary for putting it's own cover plate on. Completely braindead decision and useless product.

This hub listed does work on 1998 tracker. Looks different from factory because outside uses 2 sets of bolts the base us slightly thinner and orginal bolts will not work. Here is the bolt sizes needed to install and does not come with new hub. Outer M6-1.00×15 allen head base to rotor hub M8-1.25×25 Allen head and use one small drop of blue lock tight on each and every bolt. Make sure outer part is clocked correctly before installing and free and lock are in correct orientation during operation before fully installing. Orginal failed caused screaming noises when hot as getting up to speed because one axle failed to ever disengage manually from failed locking hub which would have destroyed the diff. gears if not replaced. KAR hope this helps someone.

Don't buy those cheap aftermart hubs $90 a piece is really cheap for factory parts. Does not come with any bolts....

The product comes not complete. It’s a unique lock and is without essential screws that are only for this lock. The product image does show it without the screws.

Used on 2002 chevy tracker zr2. Well made and works nice and smooth

Converted my 1999 tracker 2WD to 4WD, got rid of the pump-diaphragm actuator in the differential and the best option was installing some manual locking hubs. So I got these and they fit perfectly.One word of advice for 4wd converters: Get the CONICAL lugs to secure these locking hubs to your 2ND Gen Trackers. Then buy some stainless steel bolts to secure the lids of the Aisin locks. Piece of cake. You will enjoy!
