this is from a 88 323, Dont know what you saw but it looks pretty specific to me with photos even..
Removal & Installation
For front wheel bearing removal, installation and preload adjustment procedures on rear wheel drive cars, see Section 1 . For front wheel bearing removal, installation and preload adjustment procedures on front wheel drive cars, see Section 8 .
Raise the vehicle and support it securely by the center crossmember using axle stands. Inspect the disc brake rotor as described below. If the disc requires replacement or machining, inspect the wheel bearing and then remove it.
Spin the tire to check for roughness in the bearing or unusual noise. Then, remove the wheel and unfasten the brake caliper, as described above. Hang the caliper out of the way without disconnecting the hydraulic line.
Pull the rotor from the hub.
To install:
Install the rotor onto the hub.
Install the brake caliper and torque the upper bolt to 12-18 ft. lbs. (16-24 Nm) and the lower bolt to 14-22 ft. lbs. (19-30 Nm) on 1986-87 323s and 1983-87 626s. On 1988-89 323s, torque both caliper bolts to 29-36 ft. lbs. (39-49 Nm), and on 1988-89 626s and MX-6s, torque both caliper bolts to 58-72 ft. lbs. (79-98 Nm).
Install a new driveshaft locknut and torque it to 116-174 ft. lbs. (157-236 Nm) on 323s and 1983-87 626s, or 174-235 ft. lbs. (236-318 Nm) on 1988-89 626s and MX-6s. Crimp the nut into the groove in the axle with a dull tool until at least a 0.06 in. (1.5mm) indentation is produced.
Install the wheel, then lower the vehicle.

Removal & Installation
This procedure requires many special tools. Read the procedure over first, and determine availability of the special tools before you start work. In some cases, it may be less expensive to have certain operations performed by a local repair shop than to purchase the appropriate tools.
Loosen the lug nuts. Raise the vehicle and support it safely. Remove the tire and wheel.
Raise the staked tab from the hub center nut, remove the nut from the axle. Apply the brake to help hold the rotor while loosening the nut.
Using ball joint puller tool 49-0118-850C or equivalent, separate the tie rod end from the steering knuckle. Disconnect the horseshoe clip that retains the brake line to the strut. On the 626 and MX6, remove the stabilizer bar control link from the control arm as described previously in this section.
Remove the mounting bolts that hold the caliper assembly to the knuckle. Do not allow the caliper to be supported by the brake hose; support it with wire.
Remove the through-bolt and nut that retains the lower ball joint to the steering knuckle and disconnect the ball joint.

Remove the two bolts and nuts retaining the strut to the steering knuckle. Separate the steering knuckle and hub from the strut and axle shaft. On 626 and MX-6 with ABS, remove the speed sensor from the strut bracket.
The hub is pressed through the wheel bearings into the knuckle. Removal/replacement of the hub requires wheel hub puller tool No. 49-G030-725/49-G030-727 (or equivalent) for the 1983-87 626 and 323, or Nos. G49-G033-102, 104 and 105 (or equivalent) for 1988-89 626 and MX-6.
On 1988-89 626 and MX-6, if there is an inner race on the front wheel hub, grind or machine a section of the bearing inner race to approximately 0.02 in. (0.5mm) and remove it with a small cold chisel.
Remove the inner oil seal and bearing. Remove the outer bearing using a press and tool 49-G030-725/49-G030-728 for the 1983-87 626 and 323 in order to remove the bearing from the steering knuckle. Drive the outer and inner race from the knuckle with a brass drift and hammer. On 1988-89 323, remove the outer bearing race with tools 49-B092-372 and 49-F401-366A and then withdraw the outer oil seal from the front hub. On 1988-89 323, remove the bearing outer race with tool 49-FT01-361 and a press and remove the wheel bearing. On 1988-89 626 and MX-6, press the bearing from the hub using tools, 49-G033-102, 104 and 106.
Inspect the knuckle for cracks, heat damage, or rust. The dust cover may be left in place unless it is damaged. If it must be replaced, note its position before removal or scribe alignment marks. Then, install a new one using a pipe about 3.19 in. (81mm) in diameter and a hammer or press. Replace the oil seal if it is damaged or worn at the contact surface.

Inspect the oil seal for proper position. If it has moved upward, press it back into position. The knuckle should be placed so it is securely supported by its center, that is, the center of the knuckle should be aligned with the spindle of the press. Then, press in the new bearing with a piece of pipe about 2.6 in. (66mm) in diameter bearing only on the outer race.
Install new inner and outer races as required. Make sure that the edge of the race contacts the steering knuckle. Pack the inner and outer bearing with grease and install in knuckle. Use tool 49-G030-728 for the 1983-87 626 and 323 to press the hub into the steering knuckle. On 1988-89 323, use tool 49-V001-795 to seat the bearing in the hub. On 1988-89 626 and MX-6, use tools 49-G030-797, 49-F027-007 and 49-H026-103 to install the wheel bearing.
On 1983-87 models, measure the preload with a scale connected to the caliper mounting hole on the knuckle. Various spacers are available to increase or decrease the preload. Preload should be 1.7-6.9 ft. lbs.
On 1988-89 323, measure/adjust the preload as follows:
Insert the bearing and spacer into the steering knuckle and install tool 49-B001-727. Tighten the tool to 145 ft. lbs.
Connect a spring scale to caliper mounting bolt hole on the dust cover and pull on the scale to measure the bearing preload (starting rotation torque). This preload should be 0.53-2.55 lbs. for 13 in. wheels and 0.48-2.35 lbs. for 14 in. wheels. When tightening the preload tool, torque in 36 ft. lb. increments.
If the preload is not within specification, spacers are available in a variety of thicknesses to adjust it. Increase the spacer thickness when the preload is too high and decrease the thickness when preload is too low.
Install the inner and outer grease seals. Press fit the hub through the bearings into the knuckle.
Installation of the knuckle and hub is in the reverse order of removal. Always use a new axle locknut and cotter pin. On 323s, torque the axle shaft locknut to 116-174 ft. lbs. On the 626 and MX6 torque the locknut to 116-124 ft. lbs. Stake the locknut after tightening. Use a small cold chisel to stake the locknut tab. After the tab is staked, make sure that at least 0.16 in. (4mm) of the tab is in the groove.
For all brake caliper/disc removal and installation procedures, please refer to Section 9 of this manual.
