Custom Built BMW E70 X5 Limited Slip Differential. Diesel or Petrol models. The BMW E70 X5 Differential is prone to failure, this is mainly caused by a few inherent design faults along with incorrect manufacturing and incorrect tolerances when manufacturered. Due to this common occurrence, we have now upgraded to a Limited Slip Differential. This stronger and more reliable design gives the differential around a 30% increase in strength and reliability. Limited slip differentials compensate for a loss of traction in one wheel, offering you more control even when driving on slippery or rough roads. A limited slip differential increases a car’s power and speed by utilising engine power more efficiently, thus allowing for a smoother and more enjoyable drive. BENEFIT OF A LIMITED SLIP. ? Stronger more robust design. ? More control and smoother operation. ? Less axle shaft wear. ? Increased Off road capability. This differential is now ready as pictured for immediate dispatch, we now have over 100 BMW E70 X5 differential currently fitted under many X5 vehicles with many happy clients. The Differential kit includes the following and is a direct replacement of the original differential. 1x Fully Remanufactured E70 X5 Limited Slip differential with Uprated bearings. 1x New Half shaft balanced with modified UJ. 1x New Centre O. 1x New rear shaft with modified Flange hanger. Rebuild includes full strip and cleaning of internal oiling system and modification to increase oil flow. As well as a lack of lubrication to the cone bearings they become very problematic and start failing, a modification is now implemented to allow more oil to the bearings. The Modified bearings are setup in house and to my own specific tolerances. We provide the highest quality reconditioned genuine BMW differentials. The differentials are reconditioned with genuine OE components, bearings are a modified item to resolve the fault in design, fully stripped down, cleaned using our in house ultrasonic cleaner, tolerances, preload spec and contact mesh checked along with all new seals, and non consumables replaced. Currently and one of very few companies in the UK – possibly the only one – able to offer this upgrade. We have many options in respect to mods, up rated / improved parts, and processes implemented. So you can feel rest asssuered that you are purchasing a quality engineered component. The workmanship and attention to detail that goes into one of our Differential builds is bar non you will not find any corners cut here. We pride our selves on our Differentials not only internal but external and guarantee our Units for 12 months. All my Differential are built by my self by hand in house every part is scrutinized and inspected and nothing is left to chance. My Differential are fully reconditioned units which means all serviceable parts are replaced. I find my self more and more repairing Differentials that have apparently been reconditioned months prior to find out that all that may have been changed is the absolute minimum or nothing at all. All preload shims custom ground in house to a 1 micron tolerance. A properly rebuilt automotive part. Rebuild includes full strip and cleaning of internal oiling system, with modifications to increase oil flow. The item has been completely disassembled, cleaned and examined for wear and breakage. Worn out, missing or non-functioning components have been replaced with new or rebuilt components. It is the functional equivalent of a new part and is virtually indistinguishable from a new part. We’ll also guarantee our work for 1 years, or 12,000 miles (whichever comes first) on fitted Differential, 6 months / 6,000 miles on’take-away’ units and 3 months for all auxiliary parts. This will help you when it’s time to return your old Differential. This can be arranged at an extra cost. Scottish Highlands and Northern Ireland post codes available at an additional cost. The old Differential needs to be unmolested and serviceable, what this means is that the Differential needs to come complete not stripped or dismantled, and must have no holes or damage to the case. If your Differential is leaking oil from the case or has no drive, then its safe to say that the Differential is most likely non serviceable. Once the new Differential has been received simply refrain all packaging and securing fixings, these will assist you when returning the old Differential. This can be extended considerably if the Differential is a bespoke item and requires a build slot. Our workshop hours are 9.00am – 5.00pm Monday – Friday and 9.00am – 1pm Saturday.
