Hi everyone, i'm a long time lurker with a 2005 VVT Jimny with an Auto gearbox.

It had a noisy diff when we bought it and its got gradually worse to the point now where there is significant backlash in the diff and more noise than before.

From the research i've done online it seems I need a 4.090 ratio diff and haven't had any luck finding one.

Does anyone know whereabouts I could source either a recon unit or failing that something secondhand?

I'm based in South Yorkshire.

Cheers,
Andy.

Thanks Guys, I had already figured out that I needed a 4.090 diff but can't seem to find one anywhere.

Might be going down the route of replacing the pinion bearings and see if that makes any difference.

Might as well replace the diff sidegear bearings and wheel bearings while its in bits, wouldn't be that much extra work and gives peace of mind ;-)

you could use 4.3 diffs if you changed both of them to match and used some larger tyres. it would work well.

OK, so I ordered a bearing repair kit from www.rsmfg.co.uk but haven't heard anything from them. No answer on the mobile number provided on the website.

Does anyone know if they are still in business?

I don't know if they are in business but I do know they were (are?) notoriously hard to get hold of but reliable
