c ns s . R ns t . E d u ) Some indications you require a new bearing according to screeching noise (people taking an alert as you journey by) coming from the front tires area in enhancement to a grinding noise. Girlfriend can also check the bearing by first, lifting the front tire off the ground. Encountering the tire, take it at 3 and 9 o"clock, then relocate the whole tire in and out by pushing 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, opportunities are the bearing is hosed. Tools: - can of PB blaster to ease the bolts - 1/2 in journey breaker bar (or dubbed a flex head handle) - 32 mm hub socket (for 1995 traveler with ABS, 30 mm because that my 2004) (you can rent this native Autozone) - Bungee cord or item of rope - 3/8 and also 1/2 journey socket set (english/metric) - 1/2 in-to-3/8-in drive converter (or called an adapter). A global will also do - on slide hammer (you deserve to rent this indigenous Autozone) - 1/2 journey torque wrench (you can rent this native Autozone) approximated Time: 3hrs (Most of the moment is spent acquiring the rusted 14 mm (15 mm top top 2004 Explorer) bolts loose)
Before starting the job, spray every bolts with PB blaster to assist loosen them.Before elevating the truck, you must loosen the hub seed so you can remove it v your fingers (32 mm on 1995 and also 30 mm ~ above 2004) and the lug nuts (19 mm). At the end, when putting it all back together, be sure the nut is tight before applying the truck "load" come the bearing (i.e., once lowering the truck down from the jack stand). The is finest to do this with a 1/2 inch breaker bar. Climate lift the truck and also pull off the tire.

girlfriend now need to remove the brake assembly. There space two short bolts behind the caliper. Remove these and also pull the caliper off.
The caliper come off best when the rotor is flush with the bearing hub assembly. Girlfriend can force the rotor to be do the washing up 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 keep the rotor in one place. As soon as the caliper is off, you need to suspend it come the frame someplace with a bungee cord. Perform not suspend that by the pressurized brake line. The shoes simply pull out from the caliper assistance frame. Climate you must remove the caliper assistance frame. This is fastened via 2-14 mm bolts (that are usually rusted quite good). Once the caliper support has been removed, the rotor just slides out. Also, it can be a an excellent idea to remove the "rotor shield" (if you have one) top top the best side the the hub assembly. Once the rotor is off, the bolts because that the shield room exposed. The shield is organized in ar 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 ~ above 2004 Explorer) that host the bearing hub. A 14 mm 1/2 customs drive socket will perform the trick. However, a 1/2 customs breaker bar (or ratchet head) is too large to to the right in the space, together is. This is because the CV boot is in the way (for all 3 bolts). Before you start everything, you have to turn the wheel fully in one direction (or the other) so as to have much better access come the bolts.
I uncovered that if I usage a 1/2-drive to 3/8-drive adapter with a 3/8 customs breaker bar, I deserve to fit the socket in the space. If I had a universal adapter, I can probably use the 1/2 breaker bar. NOTE: I additionally found that on the 2004 Explorer, there really isn"t any kind of room because that this adapter. In this case, you have to remove the Hub nut and try to push the spline back through the bearing. The is, insanity the spline so that the whole assembly moves in the direction the the CV boot. Friend should be able to move the spline back around 1/2 inch or so. This will complimentary up sufficient room because that you to acquire the socket in the tight space.
The only difficulty is, there is not enough leverage (using the 3/8 breaker bar) to ease the bolts. I deserve to make the 3/8-drive breaker bar longer with a short piece of pipe.
once the 3-14 mm (3-15 mm for 2004 ExploreR) Bolts room off, you have to pull the bearing turn off the spline. This have the right to be done utilizing a "slide hammer". Mount the on slide hammer plate come the bearing hub studs. Then merely pull the bearing directly out and off the spline.

In this photo you have the right to see the spline because that the CV joint and also the old bearing on the floor with the ABS cable tho attached. Likewise you can see the 2 holes because that the caliper support bracket and 2 (of the 3) little holes because that the rotor shield, i m sorry is top top the floor to the right.
now you just need to install the new bearing end the spline. Girlfriend can attract the spline v the bearing by utilizing the hub nut. Perform not end tighten the hub nut just yet. First, you have to install the 3-14 mm bolts that host the brand-new hub in place. These must be torqued to around 125 lb-ft. Then the whole re-assembly is done in reverse order. The hub nut need to be fully tighten last (to around 175 lb-ft) v the truck tires on and also truck turn off the jack.
