Changed the mounts (well a garage did) and the hopping in reverse has gone but the juddering is still there:2Confused :2Confused My diff mounts that come off looked good, so who knows possibly its my diff then, better start saving

had my diff brace fitted aswell and all its done is make the car even noisier as now all your hear (apart from the stupid loud exhaust and the screamer pipe) is the diff whining away to itself. Stupid cars:2eek

Have you checked the ppf for cracks?

[FD3SNuttah]

cant help you with the juddering mate - but heres what "whip" means =

1.     Whip     
   
When the steering wheel was first put into use in automobiles, it was called the "whip". The whip is what you used to control the horses on a stagecoach, hence the analogy.

Many years later, various hip hop artists noticed that the Mercedes-Benz logo resembled a steering wheel. They then proceeded to use the old term "whip" to describe any Mercedes-Benz vehicle. The term has now been generalized to classify any expensive automobile.

Check the new whip, thug! I dropped 300 G\'s on this V12, now I\'m ballin\' like James Bond when he was still gettin\' pussy!

I know this is not much help.:o

When i collected my car from one the sites vendors. I had the same thing. If your in fifth say doing 50mph come off the power. The car slows when it gets to just below 40mph the car judders. Back on the power also OK.
Was lead to belive by the vendor this was common tranmission slack. Replaced the gearbox oil with redline heavy duty. Now judders closer to the 30 mph mark.

50 miles atfer that the engine blow a coolant gasket.

My car likes to judder quite badly at 30mph in 4th (when I\'m off the throttle). Fine when on or braking.

So what\'s it likely to be??

I\'ll get the front Diff mounts checked asap. If they are ok, is it easy to asess if the diff is shot or not?? Could the diff be low on oil (is that even possible?).

Here\'s the detail on diff and transmission oil changes....

Changing the diff and transmission fluids
The diff is easy the transmission is tricky. First I went to Home Depot and got 8 Ft of 5/8th od dia clear tubing and a plastic funnel set. That\'s how you get the oil in the transmission and differential. Now, make sure you have 3 new aluminum washers for the large transmission drain plug, the differential fill plug and differential drain plug before you start. I get mine from the dealer. I don\'t like using the copper ones that the parts stores usually carry because, at least here at the beach, galvanic corrosion (from dissimilar metals) can be a problem. Make sure you have a tube of liquid Teflon thread sealant for the small transmission drain plug and the transmission fill plug (also at Home Depot, or you can get the fancy automotive stuff at the parts store). You also need a few large metric combination wrenches and sockets I can\'t remember the exact sizes but I think they were ~22-25mm. Finally you need 3 quarts of oil for the transmission and 2 quarts for the differential. I used Redline MTL for the tranny and Redline 75-W90 for the diff.
The differential is easy the plugs are in the back, undo the fill plug then undo the drain plug. Put the new washers on the plugs, and put the drain back in. Stuff one end of the hose into the differential fill hole, push the funnel onto the other end of the hose. Stand up next to the rear of the car while holding the funnel. Slowly pour in the oil until it just begins to spill out of the fill hole. As a side note, the car should be completely level while doing all filling operations.
Now for the transmission, there are two drain plugs, one fill plug and one plug that you don\'t touch. First remove the sheet aluminum cover and set it aside. On the bottom of the transmission case is an obvious big drain plug. The other three plugs are on the driver\'s side of the transmission. The highest one has a recessed square socket don\'t touch it. Approximately below it is a plug with a protruding square socket, this is the fill plug. Behind and a little below the fill plug is another protruding square socket plug, this is the second drain plug. Remove the fill plug then the big drain plug let the oil run out. Then remove the second drain plug. You remove the fill plug first other wise the oil "plops" out everywhere except in your drain pan (you did remember to put a pan under the drain plug .To fill the trans put the new washer on the big drain plug and the sealant on the second drain plug and put them back in. Stuff the funnel in one end of the hose and ~3" of the hose in the fill hole (it just barely fits) stand up next to the car while holding the funnel and slowly pour in the oil until it just starts to spill out.

cheers

what oil is needed for the diff?
