I got my car put in for a service and while it was in asked them if they could try and work out why there was a noise in the rear end of the car. they told me that the universal joints had to be replaced so that got done and then the problems started. The car now vibrates going at 70+ KPH they replaced the drive shaft thinking that was the problem, and then some cross thingy near the drive shaft and its still doing it. It didnt have this problem before i took it in and they changed the universal joints. oh and it has a new rear axel but that was from a few months ago so thats not the problem. And the mechanics can't work out the problem.
Can anyone help me please :(

You've got a drive shaft alignment/balance problem. When replacing the U-Joints the shaft and yoke positions should be marked so they remain the same upon reassembly. The drive shaft and front and rear yoke are balanced as an assembly. Not maintaining the same alignment (assembling one or both yokes 90 degrees from it's original alignment with the shaft) can ruin the balance and induce vibration in the system. If they replaced the drive shaft the unit could still have a balance or out of round problem. Have them check the run out on the shaft with a gauge. If that's good have them take it to a shop that specializes in drive shafts and have the balance checked.

If you did not have the balance problem when you took the car in then it was something that was done while they worked on it that caused the problem. Were the wheels rotated at the time you took the car in? Do you feel the vibration in the steering wheel or all over the car? Front wheel imbalance is much easier to feel because of the steering wheel.
Have them run the car at 70 kph on the lift and look for what is vibrating.

Try runnung her up to 90. If the problem goes away, there is a wheel out of balance. If it gets louder then one of the new universal joints is bad or was damaged during installation.

Vibrating at a certain speed is sometimes just wheel balance.
Is it possible the balance weight(s) were knocked off while the car was in for repairs.
Just a thought.

i would have done the high speed wheel alignment first and balance out the tires.
