I think some backlash is ok, or mine has some. Is it a massive clonk? Definitely not a U.J .?

Re: 300 GL Good rear diff required and advise.
If you have auto transmission and the shift modulator is not doing its job, you'll get hard shifts which produce the clock. It's a relatively cheap item to replace, or you could try to adjust. They were, however, improved in about 1995, so may be worth replacing, if you have an older vehicle. Some backlash in the drive-train is normal. It's not only in the diff. The transfer-case will have some too. Also ensure that you have the same make and model of tyre front and rear. If the rolling radius is slight light larger in the front, you'll get a 'clonk' when setting off, after coming to a stop.
