    Differential Backlash

    Got it. So still on plan 'a' .. get the bits out, putting it back together with a new case (and some new bolts) and seeing how it works. Thanks

    Differential Backlash

    Limited garage time means slow progress but this isn't the bolts coming undone but they have sheered off. Any ideas why that would that happen?

    Differential Backlash

    That sounds like a plan. Thank you for the advice.

    Differential Backlash

    Not really much (any) debris that I can see. I'll get a pic of the inside of the cover in a bit

    Differential Backlash

    Quite a few of the other tab washers look like they have 'opened up' or weren't bent over at some stage. I've had the car 23 years and no one has been inside the diff in that time. I have no experience with differentials. Does this look like I should change the diff for an unknown second hand...

    Differential Backlash

    Thank you Harvey. I'd rather not fit a random second hand diff (even though mine clonks a bit) so I'll do as you advise.

    Differential Backlash

    Oh dear. I don't think the backlash matters now. I was investigating a big oil leak and found 2 U/Js were very stiff / seized and I guess that's set up vibration that has cracked the diff case.

    Thanks for confirming backlash is ok. I'll contact you about U/Js.

    Differential Backlash

    Hi, I've just taken the driveshafts out of my 3500 (I'm going to changing the U/Js) and I'm surprised that I can turn the inner driveshaft about 10mm before the other one begins to move. This feels like a lot of backlash in the diff and it clonks. Is this a normal amount of 'slop'? Thanks. James.

    New water pump and overheating problems

    I've been thinking about what Ron said about the straight impeller pumps working fine and that there must be something else wrong. Looking carefully at the first picture I can see that the impeller is pushed much farther on to the drive shaft on the new pump. I've taken a second picture to make...

    New water pump and overheating problems

    Problem is solved. As a temporary measure I've re-fitted the old pump again and cooling is back to normal again. The symptoms were caused by poor flow. I did discuss the straight impeller pump with 2 mechanical engineers at work who both said it would be much less efficient than the original...

    New water pump and overheating problems

    Thanks for the advice. Yes, it is a uk car. Will get thermostat and put it back together evenings next week.

    New water pump and overheating problems

    Ok, thanks both for the advice on bleeding the system. Sounds like I should try another thermostat and give it another go.
