I need instruction & schematic to replace rear axle bearings & seals on a 1986 4runner sr5
Hi ; i recently had the rear brakes repaired, the mechanic said I need to replace the rear axle seals & bearings as the oil from the transfer case is leaking & thus degrading the brake pads..can you help with instruction a diagram & instructions to make this repair at home or should I just bring it back to the garage & pay him the $900 + dollars hes has quoted me
Re: I need instruction & schematic to replace rear axle...
Good news mate!You don't have to touch the bearings at all !!! Just replace the seals, highly unlikely the bearings are toast, had the very same problem and advice from local repairer but another (honest) mechanic suggested to change the seals only and it worked.Remove old seals using a large flat bladed screwdriver taking EXTREME CARE not to scratch the housing, tricky bit is to replace the seals as they have to go in SQUARE to the housing, use a large socket if available or a flat piece of steel to rest against the seal and hammer in SLOWLY AND CAREFUL, ALWAYS SQUARE ! to the housing, take your time and do it a bit at a time, the further in you go the easier it gets, make a note of the final position of the old seal before removal, do a sketch or take a photograph, also take care when reinserting the prop shaft back in the axle housing not to damage the new seal. Good luck !!!

if you have a semi-floating axle ie an axle that the axle bearing is pressed on you have to remove the wheel, remove caliper if disc brakes and remove a retaining plate that holds the axle bearing in position. pull out the axle and the seal will be left in the axle housing. Replace and reverse procedures. If you have a full floating axle you have to remove the axle from the hub undo tha axle bearing nuts amnd if disc remove caliper or if drum pull the hub of the axle. The seal will be in the back of the hub as in a truck. you will need some mechanical knowledge so if you are unsure get a mechanic to advise you
you don't repair it, you replace it. jack it up, remove the brakes, and all the brake assembly from that axle,, http://www.ehow.com/way_5731956_ford-rear-brake-replacement-instructions.html
then remove the bearing cap,, cotter pin, and nut from the spindle , ( you might want to replace the wheel bearing at the same time due to the bad axle ) remove the axle bolts,, and shock bolts, from the axle beam. remove axle beam assembly
What are going to do to repair the axle? There really is no axle on front drive cars, the wheel assembly is connected to a hub that is mounted to the frame through swing arms. And, you would not take your car to a autobody shop for mechanical work. The cost of repairs depends on what is being done.
YOU HAVE TO SAFELY RAISE SUPPORT VECHICLE MAKE SURE ITS ON A SOLID LEVEL GROUND.THEN YOU REMOVE THE WHEELS THE BRAKE DRUM OR DISC.THEN YOU REMOVE THE NUTS THAT ATTACH THE OUTER SEAL RETAINER AND BRAKE BACKING PLATETO THE AXLE SHAFT TUBE.DISCARD THE NUTS.REMOVE AXLE SHAFT FROM HOUSING.WITH AN AXLE PULLER ATTACHED TO A SLIDE HAMMER.DISCARD INNER AXLE SEALPOSITION THE AXLE SHAFT IN A VISE.REMOVE THE RETAINING RING BY DRILLING A 1/4 HOLE ABOUT 3/4 OF THE WAY THROUGH THE RING. THEN USING A COLD CHISEL OVER THE HOLE.SPLIT THE RING.REMOVE THE BEARING WITH A ARBOR PRESS DISCARD THE SEAL AND REMOVE THE RETAINER PLATE.TO INSTALL - CLEAN THEN APPLY A THIN COATING OF WHEEL BEARING LUBRICANT TO THE BEARING AND SEAL CONTACT SURFACES APPLY WHEEL BEARING LUBRICANT TO THE LIPS OF THE REPLACEMENT INNER AND OUTER SEALS.INSTALL THE INNER SEAL WITH THE OPEN END OF THE SEAL FACING INWARD ENSURE IT IS COMPLETELY SEATED.INSTALL THE RETAINER PLATE AND THE OUTER SEAL ON THE SHAFT.ENSURE THE OPEN END OF THE SEAL FACES TOWARD THE AXLE SHAFT BEARING.PACK THE REPLACEMENT BEARING WITH WHEEL BEARING LUBRICANT AND POSITION ON THE AXLE SHAFT PRESS INTO PLACE.PRESS A REPLACEMENT BEARING RETAINER ON THE AXLE SHAFT AGAINST THE BEARING.INSTALL THE AXLE INTO THE AXLE TUBE.POSITION AND ALIGN THE SEAL RETAINER AND BRAKE SUPPORT PLATE AND INSTALL REPLACEMENT ATTACHING NUTS.TIGHTEN NUTS TO 32 FT LBS.INSTALL BRAKE ASSEMBLY WHEELS LOWER VECHICLE. YOU SAID REAR BEARINGS IF THIS WHAT YOU MEANT.I HOPE THIS CAN HELP.
i will tell you right off this is a job for a qualified mechanic,the axle has to be pulled off first you jack up that wheel dismantle the brakes and rotor and behind the axle hub are four bolts that hold on the axle remove them and axle will come off the rear end cover does not have to come off and the axle fluid also does not have to come out,but now that axle is out you will notice that a wheel bearing is holding the seal in place this is pressed in you can buy these as a set at the dealer but must be removed by a pro. as not to harm axle and it has to be pressed back in
You should be ok replacing the outer seal but check for bearing play or fautly outer wheel bearing before you disassemble. If to much lateral movement in axle shaft it will take out your new seal rather quickley.
