rear differential axle leak. Was told by the dealer to watch it, which I did. I also asked dealer (at each oil change) if it should be repaired. Was told not yet.
rear differential axle leak. Was told by the dealer to watch it, which I did. I also asked dealer (at each oil change) if it should be repaired. Was told not yet. I trusted my dealer. Now that the 5 yr warranty is over, they say I should fix it. Seems very unfair to me.

Not fixed. Told I need front and rear differentials. Seal is leaking. Nice car but my mechanic said to sell it. Thumps and grinds when taking off to make a right or left turn. Slowly getting worse.He said it was very costly to fix and dangerous to drive.....
Oil leak at differential. Took Caddy dealer three attempts to fix. They had to replace entire rear end housing.
