One of my fellow UK stangers just replied to a question i posted, price of having gears fitted here is expensive, but here is his reply. "Having installed my own 4.10's the ABS sensors came off relatively easily. I gave mine a liberal coating of WD40 a day before hand and no problems. If you have the time and buy Ford Racing gears the installation is relatively straight forward to do it yourself. The Ford Racing gears all seem to be set up to use a standard pinion head setting height. I ended up using the original shim again and set up checked fine. No whine!" Does that seem about right, if i use Ford gears its that easy? And here's a quote to fit them: "We can fit 3.73's for you. That would work out good all round. Labour is between 6-8hrs, we advise that ABS sensors my need to be replace as there is always chance of damage when removing the shafts. The gears are Ã‚Â£179.95+vat, Installation kits starts at Ã‚Â£38.95+vat this includes shims and seals etc, the next kit up includes new pinion and carrier bearings and then the most expensive kit includes rear shaft/wheel bearings. Our labour rates are: Mechanical Ã‚Â£45+vat per hour (10% discount when parts purchased from Adrenaline) Fabrication Ã‚Â£40+vat per hour. Look forward to hearing from you. Danny Bates Adrenaline Race & Performance Ltd" Dont forget to multiply the Ã‚Â£'s times 2 to get the price in $'s.
