MGB Differential with too much lash

[DrEntropy]

After quite a bit of time and LOTS of miles, the diffy in the MGB is exhibiting some real gear lash. Anybody have a "chunk" (the later ring and pinion, not the "banjo" type) they'd want rid of? Looking to rebuild one on the bench and do a swap-out rather than have the B inoperable in the interim.

Hey Doc, I got one that has a little slap and banging around back there too. But I'll just keep it because I don't think you'd want this one either. Anyway the 'B' is slated for a full redo this coming winter so I'll need it then. Good luck with yours.

Over the years I've only seen two of these diffies with serious lash issues. The things are near bulletproof, IMHO. I'll admit I neglected this one, it sat from around 2005 'til last year mostly unused. With well over 100K miles.

Doc, i don't have a lot of experience with the B rear gears but mine is pretty loose. Sometimes I wonder if it will hold till this winter when I do the resto. But I do agree the MG rear gears and for that matter all the LBC rear gears seem very robust. My BJ7 Austin Healey had perfect rear gears till I decided to go to the 3:54:1 ring and pinion. After two different sets and two different pro builders i now have the 3:54 ratio I wanted, but with considerable noise and considerable looseness. But I'm not going to pop for another set again. I have been beating the dickens out of those 3:54s for 4 years and haven't broken them yet. One of the things I am enjoying with the B is that it is so shabby and so run down that my attitude is that I can't hurt it. I lay tools right on the fenders with no fender aprons to protect them and I slam the hood which I had to adjust to a rather high fit just to get it to latch consistently. Everything I do with it is just fun because it is a true beater. But also, I've got it purring like a kitten right now. Stay warm and cozy down there in Florida, its just getting into the high 60s and low 70s here in Pa. FINALLY! Say hello to PD for me if you ever catch up with him.

I see you saw the meet-up post.

I'm bein' mosquito bit just sittin' here at the desk in the garage. Intended to R&R the A/C compressor on the neighbor's G7 Infinity but he was sold the wrong compressor. There's an amazing amount of *stuff* shoe-horned into the engine bay of that thing. Couldn't see enuff of the mounted unit until I'd taken a boatload of other pieces out. Then it was: "Oh, carp!" And putting all the pieces back together. Modern cars are much too complex for my taste. Give me something like a B, the Spider or my Lotus cars. I can see and NAME everything in 'em. :wink:

I got ya Doc. Understand completely. You are very persistent. I gave up on new fangled cars. this is suppose to be fun. If it has a computer and fuel injection I don't touch it. Ya know if you wanted to keep on wrenchin I would bet you could find quite a few "COLLECTOR CARS" around there that just need a little TLC now and then. You know the stuff, with DISTRIBUTORS, and POINTS and CARBURETTERS. The stuff that's fun to work on. ...... Maybe we should move this conversation to the PUB?
