Corona RT142 diff problem any help would be appreciated!

[Mr Multivalve]

Thanks for the replys, the front input was so worn and loose it just dripped the oil out.

Thanks heaps for the diff wilbo so much better than the piece of shit that was in my car LOL. Here is a pic of her cleaned up a bit and in the car. Heaps more responsive nice pickup. 2600rpm at 100km which is alright.
I shit myself though as i was coming onto the onramp to the highway I thought I was doing about 100km, I looked down and I was doing 140km.

Make sure you speedo is still correct.. By changing the final drive ratio, it changes the speedo reading as well. Only likely to be a few km's, better to know.

Ok thanks, any way I can calculate it exactly?

Go on a Highway with a mate in his car.

[Mr Multivalve]

Appart from that as that was my method of finding out

Another thing to consider is that an F-series MA61 diff has a clutch -type lsd centre; an RA65 F-series diff is the same case but an open centre.

So if the diff shop replaced your lsd diff with an open centre diff, you got screwed.

[Mr Multivalve]

Yeah well they are looking for a diff for me so I will give them a call and tell them that I want another ma61 lsd diff.

Will have to see if they try to screw me over

Put the info in there for your new and original diff ratio, it will tell you how far out the speedo will be at the top of each gear.
