Perhaps you should ask the question here;www.mx5oc.co.uk/

Might be worth emailing HJ so your case (assuming you have a failure) can be noted, so if others have the same problem ithey too can be listed in the reviews section.

I'd like to undo the level plug on the diff, see if there's any or enough oil in it before the dealer gets his mitts on it.

Interesting MT.

I've had a couple of cars with LSD's and have found them not as good as one might think from the hype, others may disagree.

The Hilux had a LSD and was of course RWD unless you locked the centre diff bringing the front diff into play, so for all normal road driving it was RWD only, the LSD rear diff was very stiff to operate by hand with one wheel off the ground (would take all my strength to turn the wheel by hand with wheel fitted), and this translated that in slippery conditions you weren't that far from a locked diff situation, whether this changed when the diff oil got warm i couldn't say.

The demo we were hoping to buy had been spun out and written off by one of the sales team, the new model we purchased (better value with the deal we got) only confirmed things.

With a normal rear diff on something like that pick up any power applied on a wet bend would see one rear wheel spin up (live axle), leaving the steady outside wheel keeping the vehicle on track, with the model we had the vehicle proved seriously tail happy because that inside wheel wouldn't spin at all and tail out slides were too common for comfort, this saw me swapping from the OE Pirellis within 1000 miles and fitting summer General UHP and Vredestein Wintracs on for the two obvious seasons (bought a used set of spare alloys for the Vred winters), this improved the vehicle considerably.

If i could turn back time i'd have gone down one model in the range and had a normal open rear diff instead but with the facility to lock it electrically when needed.

This problem may have had some bearing on the Hilux model we owned failing the Scandinavian 'Elk Test', though Mr T dropped a clanger when speccing Invincible model because they put smaller tyres on than rest of the world got, something i put right when i swapped rubber, Toyota had a massive knee jerk reaction to the publicity and instigated a recall for different size tyres and wheels altogether, something i refused because the problem was already cured on ours.

Does any of this LSD in practice ring a bell with your experiences, have others found certain cars to need very careful tyre choices?
