You have to raise vechicle.use jack stands.block rear wheels.apply parking brake.when loosen axle nut.its more easier to leave wheel on.let vechicle weight hold wheel from turning while you loosen axle nut.you need to get a 1/2 break bar or large ratchett wrench with a deep socket .you need to buy socket use to remove axle nut a regular socket would probably break.when you remove the axle nut.remove brake caliper and brake pads.set them aside dont disconnect brake caliper.get a piece of wire to hang it out the way.dont use brake hose.could damage it. remove brake caliper support bracket then the rotor.get a hub removing tool remove hub.then loosen hub and bearings bolts .then remove shield hub and bearings assembly with O-ring.disconnect ball joint from steering knuckle using the proper tool.remove the halfshaft assembly and tap the seal from the steering knuckle.remove the steering knuckle from the hub.now that drive axle out the way.get the seal removing tool.its a flat tool with two hooks on it.to pry seal out transmission.or you can use a small chisel to clapse the seal but be careful dont damage the seal housing.when installing new seal coat it with transmission fluid.drive it in using a large socket.if you are reusing same axle replace circlip on the end of it.now putting back together.install a new hub and bearing seal in the steering knuckle with a seal installer tool .install steering knuckle to the strut.lubricate the hub and bearings with grease.install halfshaft.connect ball joint to the steering knuckle .install a new O-ring around the hub and bearing assembly.install hub and bearing assembly into the steering knuckle.tighten bolts to 75 ft lbs.install rotor then brake caliper support bracket bolts 120 to148 ft lbs.this is mounting bracket bolts only not the caliper bolts to brake shoes.put brake shoes and caliper back on torque 38 ft lbs.install shaft washer the axle nut to 180 ft lbs.tighten much as you can.before setting car on ground.to torque it to 180 ft lbs place car wheel back on set it down so the car weight keep wheel from turning.i hope this information works out for you good luck.and work safe.

Remove the drive axles and then pry out the old seal and then press in a new one. Where are you located?

Why is my transmission fluid leaking around the seal?


If you bought a new axle and seal, it shouldn't leak. Unless they nicked the seal putting the axle. When using a used axle, it needs the rust sanded off before installing. That rust will eat up a seal.

Hi i have a 93 buick lesabre that is leaking atf badly seems to be comming from right where the motor and transmisson join together im thinking torque converter seal and im wondering how difficult a job...


I worked on buicks at a dealer for 15 years and never saw a torque converter seal leaking...if its trans fluid that leaking i would suspect a front pump seal in the trans,If is not trans fluid make sure its not the back of the intake manifold leaking down the bellhousing seaming to leak from the trans. ..If oil maybe rear main seal... No special tools needed really just make sure you support the engine safely if you are going to remove the trans.....

Drive axle removal cant get lose from transmission its on a 93 buick


Put a pry bar between the axle housing and the trans.Then hit the end of the bar with a quick hit from your hand ,It will pop right out.There's a snap ring on the end,it keeps the axle from falling out.You did unhook the lower control arm for clearance,didn't you?Some remove the hub instead.To put the axle back in be sure to put some oil on the seal surface of the axle so you don't cut or burn up the seal.The axle will go in easily with a quick push.Good luck!

I have a 1998 Buick Lesabre that keeps losing antifreeze.


Buick 3.8's are notorious for intake manifold leaks. If you are sure you are not leaking externally (look under the alternator and on the top of the transmission), it could be an intake manifold leak. I've replaced mine...I didn't think it was too hard a job for an amateur.
It could also be a head gasket, but the intake leaks are much more common.

Does anyone know if the steel seal works for blown head gaskets?


I used steel seal on a 93 Mazda pickup, it had 130,000 miles and it smoked like a steam engine out the tailpipe, I used the product and now have 189,000 miles and still running great.
