While many differentials are some of the strongest parts of your car, they do wear out and will need replacing. One sign that your diff needs replacing or reconditioning in a rear-wheel drive car may be a whining sound from the rear.

Surrounding parts will also suffer damage when you have a faulty rear differential. Cost to you needn’t break the budget though, don’t worry!

We have a range of affordable options for a wide range of stock. We’re ready to repair that sudden failure of your rear differential. Cost can also be kept down through our reconditioned service or exchange units? We guarantee speedy turnover and prompt delivery to ensure that you and your customers are satisfied.

  • A GREAT big thank you to the amazing and professional staff at Diff Trans. After supplying and installing my gearbox in my VE Commodore, i can not recommend more highly of this company. The staff were so respectful toward me which is quite uncommon and hard to come by being a female and kept me involved every step of the way. Your dedication and hardwork is very much appreciated!! Will definitely be recommending you to family and friends.
