Four years later, I want to thank everyone for this post! This is exactly what I was looking for. I have a 2006 Range Rover Sport Supercharged. I bought the unit with 160,000 miles on it and with in a few months of buying it, the Rear stabilizer bar froze in the open position. Due to the expense, I chose not to replace it but tried to keep fluid in the reservoir just like JoeDQ1 above mentioned. Well last week (198,000 miles) the Anti Roll pump imploded and again at $1400 and no aftermarket options, I'm not investing that much into a vehicle already on it's last leg.

I had the thought of bypassing the pump, but did not know how to figure out what size belt to buy. This post solved that issue in about 5 minutes! I have successfully installed the new belts and just waiting for the battery to charge up (My wife drained it when the secondary belt broke) to see if we are back in business! I'll post back later with the final outcome!

Thanks again for posting your experiences and knowledge!

Just wanted to post the results of the Anti-Roll pump bypass project. We have been driving the Rover for a week now and it is working great! The shorter belt recommended above is a brilliant idea!
Thanks to all!

@Kory, sorry I missed your post 4 months ago. Belt part number LR #PQR500330 as mentioned further up in the thread. You can cross reference on google for many alternatives or your local part's store can give you options as well. I Just bought O'riely's house brand as it was the most affordable, which will still outlast my Rover.

@Ade773, I didn't even remove the pump, just bypassed it with the shorter belt. It helped that when my pump imploded, the shaft was angled away from the belt route. I have been driving for 6 months now, even a couple of long distance trips and it works great! I do have the constant suspension dash light on, but it has not triggered any other issues, codes or alarms. I have read that you can have the dealer re-program the vehicle so it thinks it does not have the ACE/DSC, as there were vehicles from the factory without it. But I have not checked into that.

Good luck!

Can i do this to my 2006 range rover sport supercharged v8 4.2

Yes @Hugo auturo marquez, @Roman NJ is correct, my vehicle is a 2006 RRS Supercharged. The engine is still running strong, except now I've got a oscillating thump in the left front drive train. Haven't found the cause yet, but I suspect Wheel bearing, CV Joints, steering rack or who knows maybe differential. That really narrows it down doesn't it? With about 205K miles, I suspect components will be failing one by one!

Red duk mine has 152000 mikes if i do the short belt replacement will it drive safe or it will it mess up the occilation thump ?

Hey @Hugo arturo marquez, Sorry about my last post, that must have been a bit misleading...
The oscillation thump is not related to the belt replacement. It's just a sign of other components wearing out that were probably not replaced based on the maintenance schedule.

The engine is still going strong and does not rely on the ACE/DSC pump to function. The stability control was simply an option offered on some vehicles, so a RRS will certainly run and drive just fine without it. Good luck in your project!
