</head><body><p>Hello, everyone.<br></p><p>Spent some quality time with the front apron on the TR3, so I could replace the key and fan hub that had come loose. Then did the winter maintenance: grease, oil change (engine/tranny/OD), packed wheel bearings, interior conditioning, etc. <br></p><p><br></p><p>Rear brakes show differential oil leaking into the drum. Expect that means dropping the differential/axle to take to the machine shop to break apart, then install the new seal and put back the hub and so on.<br></p><p><br></p><p>Rather than drop mine, am thinking of getting a used one somewhere so I don't have to wait for it to be fixed to start driving. Any advice whether I can fix the seal without going to the machine shop? If no, might pick up a used differential/axle to rebuild, so what are the options: would a TR4 fit? (One is available on Craigslist locally.)<br></p><p><br></p><p>Thanks, everone,<br></p><p>Terry Smith, '59 TR3A TS 58667<br></p><p>New Hampshire<br></p></body></html>
