c i s . R i t . E d u ) Some indications you need a new bearing loud screeching noise (people taking notification as you journey by) coming from the front tire area in enhancement to a grinding noise. Girlfriend can also check the bearing through first, lifting the front tires off the ground. Dealing with the tire, take it in ~ 3 and also 9 o"clock, then relocate the entire tire in and also out by pressing in at the 3 o"clock position and pulling out at the 9 o"clock position, simultaneously. If over there is a most play when doing this, chances are the bearing is hosed. Tools: - have the right to of PB blaster to loosen the bolts - 1/2 in drive breaker bar (or dubbed a flex head handle) - 32 mm hub socket (for 1995 traveler with ABS, 30 mm because that my 2004) (you deserve to rent this native Autozone) - Bungee cord or item of rope - 3/8 and 1/2 journey socket set (english/metric) - 1/2 in-to-3/8-in drive converter (or called an adapter). A universal will also do - on slide hammer (you deserve to rent this indigenous Autozone) - 1/2 drive torque wrench (you have the right to rent this indigenous Autozone) estimated Time: 3hrs (Most of the time is spent acquiring the rusted 14 mm (15 mm ~ above 2004 Explorer) bolts loose)
Before starting the job, spray all bolts with PB blaster to help loosen them.Before elevating the truck, you must loosen the hub nut so you deserve to remove it with your finger (32 mm top top 1995 and also 30 mm top top 2004) and also the lug nuts (19 mm). At the end, once putting that all back together, be sure the nut is chop before applying the van "load" come the bearing (i.e., once lowering the truck under from the jack stand). The is best to perform this v a 1/2 inch breaker bar. Climate lift the truck and pull off the tire.

friend now should remove the brake assembly. There space two brief bolts behind the caliper. Remove these and pull the caliper off.
The caliper comes off best when the rotor is flush v the bearing hub assembly. Girlfriend can pressure the rotor come be flush by using one of the 19 mm lug nuts (as viewed in pic). Tighten the lug seed on the stud the opposite the caliper. This will save the rotor in one place. Once the caliper is off, you should suspend it to the framework someplace with a bungee cord. Execute not suspend that by the pressurized brake line. The shoes simply pull out from the caliper support frame. Then you need to remove the caliper support frame. This is fastened via 2-14 mm bolts (that room usually rusted quite good). As soon as the caliper support has actually been removed, the rotor simply slides out. Also, it might be a an excellent idea to remove the "rotor shield" (if you have actually one) top top the appropriate side the the hub assembly. As soon as the rotor is off, the bolts for the shield space exposed. The shield is held in place by three small bolts. A 1/4 customs drive and metric socket can quickly remove these.
currently it"s time to remove the 3-14 mm bolts (3-15 mm on 2004 Explorer) that organize the bearing hub. A 14 mm 1/2 inch drive socket will do the trick. However, a 1/2 inch breaker bar (or ratchet head) is too big to right in the space, together is. This is because the CV boot is in the method (for all 3 bolts). Prior to you start everything, you should turn the wheel totally in one direction (or the other) so as to have far better access come the bolts.
I uncovered that if I usage a 1/2-drive to 3/8-drive adapter through a 3/8 customs breaker bar, I have the right to fit the socket in the space. If I had a global adapter, I could probably use the 1/2 breaker bar. NOTE: I additionally found the on the 2004 Explorer, there really isn"t any room because that this adapter. In this case, you have to remove the Hub seed and shot to press the spline ago through the bearing. That is, tap the spline so that the entire assembly moves in the direction the the CV boot. You should be able to move the spline back around 1/2 inch or so. This will complimentary up sufficient room for you to obtain the socket in the chop space.
The only difficulty is, there is not enough leverage (using the 3/8 breaker bar) to ease the bolts. I have the right to make the 3/8-drive breaker bar longer with a short piece that pipe.
when the 3-14 mm (3-15 mm because that 2004 ExploreR) Bolts space off, you should pull the bearing turn off the spline. This have the right to be done making use of a "slide hammer". Mount the slide hammer plate to the bearing hub studs. Then merely pull the bearing straight out and off the spline.

In this photo you can see the spline for the CV joint as well as the old bearing on the floor through the ABS cable still attached. Also you can see the 2 holes because that the caliper assistance bracket and 2 (of the 3) tiny holes for the rotor shield, i m sorry is on the floor to the right.
now you just need to install the new bearing over the spline. Friend can draw the spline through the bearing by making use of the hub nut. Execute not end tighten the hub nut just yet. First, you must install the 3-14 mm bolts that host the brand-new hub in place. These need to be torqued to about 125 lb-ft. Then the whole re-assembly is excellent in turning back order. The hub nut should be fully tighten last (to around 175 lb-ft) v the truck tires on and truck off the jack.
