Hi, does anyone have experience of noisy diff problems & solutions to fix & costs involved?

my xf is a 2014, are diff problems common?

going to main dealer will be extremely costly, are recon diffs any good or rebuild? I’d be grateful for any advice.

 

I had a main Pinion leak from my diff (2014) 3.0 XFs. You maybe saw on here. Got it fixed quickly as the oil is so thin, doesn't take much for it to run dry, also only holds a litre. Stealer wanted arm and both legs to fix but got lucky with a friendly AA man. Good luck.

Thanks Golfy!,

I had thediff filled with oil & still noisy whining, was yours making a noise or how did you know you had a problem?

I too have had arm & leg quotes to right rebuild the diff or to put swap it for a reconditioned one.

What did Aa man do to fix it?

Thought I could hear a noise, so got it up on a ramp, the casing was wet. Then drips on the monoblocks. The noise turned out to be the new Dunlops, which are way noisier than the cheap rubbish that was on it when I got the car. It's freaky as at 90mph under load it changes drone. Was sure it was the diff, but was wrong. At least no dripping on mono blocks now.
