BMW E39 S62 V8 M5 Powerflex Subframe Bush Inserts DIY How To Guide

- Welcome along to another How To DIY guide for your BMW E39 M5.
Today we will be installing Powerflex Polyurphane Subframe Bush inserts in to the OEM rubber rear subframe bushs.
The purpose of this is to reduce any forward movement of the subframe, completely erradicate the subframe twisting motion under hard acceleration (where the rear of the subframe is forced down to the road and the front of the subframe is forced up to the chassis) which in turn causes the phenomenom of Axle Tramp.
Grab yourself a drink and see how you too could complete this little upgrade in less than the time it takes to go and do your weekly food shop!
Just went out and attacked this project on my 540i, just under 3 hours from garage open to garage close, good video!
Glad it was of help for you. Great quick upgrade to help stabilise the subframe 👍👍
Great video Paul!! Compliments for being clear, informative and... of course because of pretty educated tinkering with the right model of car!
I've seen how relatively easy some fixes are that I've had done by my E39 M5 expert. Getting inspired doing next fixes myself.
Sooo, keep them videos coming!
Cheers Mark - Its great to know that my dull Yorkshire tones are helping others do things that they might not of considered before. Keep a look out for the next video which will be fitting a short shifter kit using all BMW OEM parts :)
Paul Simon well TBH I've been considering doing repairs and upgrades I never considered doable for non car technicians like myself.
Installed this bar between the spring struts myself and felt proud, after that next projects felt easier than before.
Inspired by your vids my friend, keep 'em coming!!
Great video. Could you tell me how many hours it would take to replace the actual rear sub frame bushing? I suspect mine are completely shot as I’m getting really bad vibrations through the car even after new suspension, wheel balancing etc. Is it a big job? Thanks :)
You just fixed my car thanks !
if I have OE worn old bushings, is it ok to use inserts instead of installing new bushings?
You could do, but it won’t fix the problem of worn bushings.
Another grear Vid, I am determined to gear up the M5 like this
Simon can you make a video on how to get the e39 m5 on four jack stands?
I could do, but I only use 1 pair at a time for the work I need to do. It's not difficult to do though.
Paul Simon can you make a short video for it though? How to lift the back end and front end and set them on jack stands... independently.
Hell no. Lol learn to jack a car first
So what’s the best? Full poly or part rubber and part poly like you have?
Very much depends on what you want to use the car for. Dedicated track then full poly, but for mixture of road/track then the inserts are great.
@@WestinghouseProductions ok. I mainly drive on the road. But, have plans for trackdays. So I will go for part poly rubber👍🏻
Great video! I have an e46 drift car with worn sub frame bushes, would installing these be a quick fix? The car is a very cheap track car so want to spend as little money and time as possible!
Rob Lyons I’d be looking for the chassis cracking on the E46 where the subframe mounting points are before spending any money. It’s a well known issue on all the E46 range.
After more than a year with this installed, what is you assessment of this product?
My M5 has a strange slack feeling at times on the freeway....after I've been on throttle, then coast and maybe brake.... the back on the gas, I'll feel a knock or what feels like driveline slack....almost like a slipping before it engages. You can feel it in the chassis.
I've replaced the entire driveshaft and differential bushings. Do you think the subframe bushings could be the cause of this feeling? I think this might be what you're describing in the intro to this video. I plan to do the bushings but wonder, do I need these inserts or would OEM bushings be ok on their own?
Have a look at engine and gearbox mounts. If the engine mount on bank 2 side of the engine is defective then it can allow the engine to twist on its axis and cause the issue you describe 👍
@@WestinghouseProductions thanks sir!
Poly to hard imo. Sway bar bushes only for me.
These are poly, but they're mushy poly, not the solid stuff that you'd use for control arms or whatever.
Good video, but strong accent makes instructions almost impossible to follow, for some peoples like me.
