How hard is a Half shaft replacement? Can you give me a general break down?ANY special tools needed?

DO I NEED ANY SPECIAL PULLERS OR TOOLS TO PRESS FIT ANYTHING?

Most cars I figure are similar but I am doing half shafts on the front of two subarus. One an 82 and the other an 93.

What all has to be disconnected? Just a general break down I am waiting on a afctory manual. So just want to know a rough idea what to expect. Ball Joints,tie rods,suspension,hubs???

Also does a half shaft just slid out of the spline?

DO I NEED ANY SPECIAL PULLERS OR WAYS TO PRESS FIT ANYTHING?

Only special tool that jumps out is a ball joint separator, (looks like a tuning fork). Remove the lower ball joint key and nut, remove the axle nut then place the separator between the steering knuckle and the ball joint and smack it with a hammer. Once the ball joint is free, push down the lower control arm (you will probably have to loosen and remove the anti-roll tube connector if equipped). Remove the outer tie rod the same way, grab the knuckle and pull outwards and the axle should slip out of the hub assy. After that, the axle will usually slip out of the transaxle (sometimes you have to GENTLY pry the axle a little). STOP HERE. At this point you will be hundreds of hours and tens of dollars ahead to simply replace the ENTIRE axle shaft with a rebuilt unit. It goes together just like it came off vs having to disassemble the shaft, replace the orbiting bearings, grease, boots and joints. Your vehicle may not be that simple — actually nothing on a Subie is as simple as say a Nissan Altima, i.e; brakes may have to be removed, etc. but the basic principal is the same. Always buy new cotter pins for reassembly!

  2. The swap shouldnt be that hard, you will need to remove the wheel, calipier, rotor, and a spindle nut. basic tools the only special deal would be a big socket, for the spindle nut around 30-32 millameter. It would be a good idea to replace the seal in the trans tho, while you have it apart.

  3. Not hard. Just buy a pickle fork, cheap, <$10, to separate ball joints and tie rods. Have you never heard of Chilton’s repair manuals, at the library? Or Haynes, or Motor? They will give you detailed step by step instructions, and at library they are free. Or buy one for you specific car at auto store for $10.
