Hi Freelander experts I need your advise!

I have a Freelander 1- 2 Litre diesel (year 2000 3 door) recently my control system for the 4x4 broke and needs replacing however its more expensive than the value of the car therefore I have had my diff removed completely making the car 2 WD only. The mechanic then told me not to tow with the car any more as it won’t be able to perform.
The weight I am towing is 1 trailer weighting 870kg approx and a pony weighing 430kg approx. I have never towed 2,00kg with it and personally I don’t think it could.

Please can anyone advise if I am safe to tow this weight or how losing my back wheels will affect me?
Can I still tow the above weight safely? ( I won’t be towing in pouring rain or ice).
Thank you in advance!

 

2500 pound limit per the manual, which is 1134 kilograms. You are over spec to begin with on a perfect vehicle.

 

Thank you
