Hi all.
Just noticed an oil leak on the concrete where the rear diff is on our mazda bravo.
Any ideas why this would happen ?

hi
is it leaking from the front shaft seal or the plugs
check the plugs with a spanner they may be loose
mud may have got into the front shaft seal and cut it out
done any mud driving?
have you done any
rock driving?
look for a bash mark or crack in the housing
check to see how much oil is in it the plug thead level is the correct oil level with plug out
i've done 137000km with out any diff problems in all kinds of terrain including a lot of rocky outcrops

Somebody with a Landrover has parked on your driveway..?
How old is the Bravo...15 months or 15 years...?
Is it wet at the pinion..?.., is there oil flung under the body..?..is it wet at the fill plug, the drain plug or the breather..?
Plenty of questions that may need a look under the vehicle to help ascertain where the leak is from.

Most Toyotas crash because the driver only has one hand free for driving.

Get the overalls on and under you go !
Where on the diff, is the oil coming from ?
May only be a seal, at the filling or drain plug...if so it's a cheap fix.
Just how much oil is leaking ?.......just a drip or heaps.. ?
Cheers Bucky

G'Day Lynz,
Once you've identified the source of the leak you may still need to do a little checking to find the cause of the leak.
It is entirely possible that a leak from the pinion seal, or wheel/hub seals for that matter could be caused by a blocked diff breather.
As
well as the possibilities noted in earlier comments
check the breather is clear, and if remote mounted confirm the hose to the breather is free of restrictions.
Good luck.
Rob.
