The front differential rear seal has been replaced three times, constantly having to add oil- they only just found the problem a year after the problems started. Have had to pay to readjust the alignment on the truck more than once. The repair order states Cause: axle housing lreaking at output pinion weld areas. Any info? Thanks in advance :)
Neither. You do *NOT* want to turn off the ignition, and there is no such thing as an emergency brake. ALL of the brake systems will not all fail. Your service brakes, that pedal for your feet, has a double system. When it has a failure it will be a partial failure -- you will lose front-right/rear-left or the front-left/rear-right and the other system will slow you down half speed. Remove your foot off the accelerator will slow you down using engine braking. Manual or auto you can slam the transmission into low(er) gear(s) to slow down the car. Third system will be either your hand brake or the parking brake if it is and pitiful vehicle. The hand brake is *NOT* the emergency brake. It is not just for emergencies. It is used every time park. It is used while driving, especially with a manual transmission.
They're both wrong. Neither one is right. Keep the ignition on. Shift into lower gear. Gently apply the emergency brake, without pulling hard, and keep the release button down so that you can unapply it if you pull it too much and lock the wheels.
Emergency brake, downshift to a lower gear, aim for something soft. Do not switch off the ignition for the previously stated reason.
they are saying that the welds are leaking?.well, you can try some J.B. Weldi know it sounds cheap, but it might work.clean the area really good and try to take it down to the metal and apply J.B. Weld or some kinda of sealeralso make sure that the axle breather is not clogged, causing pressure in the diff.the best repair would have the axle housing replaced, but you are talking big bucks nowif you just keep the diff. full of fluid, you could drive it forever like that.
A defective rear axle housing can prevent power from getting to your axles. In effect, you will not have any power or torque to that set of axles. Generally, the problem is not severe. I have run from Golden to Vancouver on a set of axles that were useless because of the diff. What the mechanics did for me temporarily was to take out the wheel seal bearings and the wheel seal and filled it up with oil. Essentially that set of axles was freewheeling and dead weight. However, obviously it is illegal to run permanently with it like this and it does need to be fixed. My advice to you would be to rebuild the diff housing to correct the problem. One step further would be to take the whole axle out and rebuild it it from the driveshaft to the diff housing to the wheel seals and wheel bearings. This would be an expensive repair no matter which way you do it. It depends essentially on the income that this truck has provided for you and if there is life left in it to regenerate the income that you would have to spend. A trade in might even be better. If it cannot be fixed as there are leaks at the welds, the you will have to buy a new diff housing. Anyways, I am not a mechanic, but hope this helps.
