HTML-код
- Опубликовано: 19 окт 2022
- My notes:
-There are some oddball bolt sizes so make sure you have:
T30, T60, E18, 6mm Allen, 16mm, 21mm
-Get Etorx bits in ½” because the subframe bolts are probably seized
BMW tells you to repair the following bolts:
All 4 subframe bolts ( I highly recommend )
All 4 bolts on the front subframe mount ( I highly recommend )
Rear diff mount bolt
All bolts on both V braces
Torque Specs:
-4 bolts on front diff mount - 120nm / 80 ft lbs
-Rear diff bolt - 210nm / 15f ft lbs.
-Vibration damper on rear bolt - 19nm / 14 ft lbs
-Rear diff bracket - 120nm / 88 ft lbs
-4 subframe bolts - 108nm / 80 ft lbs
-6 guibo bolts - 55nm / 40 ft lbs (+ 90 degree)

This is pretty crazy bro! I need to have mine done as well! I usually perform all mods/maintaince work myself, but with how elaborate this is, I think I may find a shop that is able to do this!
Great Video!
Did that yesterday. Thanks for the tutorial. I did it even easier and didnt have to lose the driveshaft. With the press kit I just pressed out the old bushings from the front bracket while hanging on the drive shaft. Biggest pain was the opper bolt on the rear bracket... Car is now perfect :) No vibrations under acceleration!
I'll be doing this soon and won't be removing the driveshaft as well. Hope this will take care of the rear clunk i'm hearing on my f80.
What bushing press did you use? :)
The dual mount bracket looks a great solution, good job and tutorial. Is this job worth doing on a 2019 car with the later bush? Thanks
Thank you so much for the video! This video definitely was the most straightforward install I’ve seen for this.
Wow great work, if bmw says to replace the bolts may be TTY and stretch when installing
You didn’t want to go with a bracket to raise the diff to keep the drivetrain angles in check?
Thank you , Was the wheelhops elimintaded? And The "clonk" elemineted ? :) or maybe i will do the double bushing on the back diff ? Or maybe its overrated for dailydrive..
The clonk is gone now. I don't think I experienced much wheel hop.
This might be the one mod I don't have on my car. I'm jealous your quick jack doesn't bleed like a stuck pig.i love my single mid pipe and mad max exhaust.
Thanks for the video! This is my next big project on the car. One question though. I was going to use 4 jack stands with BMW lift adapters, do you really like the quick jack for this work, or did it get in the way? (other than the first brace mention)
The Quickjack is easily the best investment I have made as a car enthusiast so far. Well worth it and definitely not in the way.
@@tuned_auto : You pushed me over the edge I have one coming the first week of Nov. :)
@@BlackEyeIII Yes 🤙 Crazy enough they sent me 2 quick jacks 5000s by accident so I sold one at a discount to a local detailing shop
How is the wine? I just changed mine to the ecs bushings and I hear a lot of wine
@@christopherpersaud8472 no wine at all. Sounds same as stock
Are there any downsides to utilising both bushes on the rear of the diff?
Depending on the bushings you use, the additional stiffness could introduce more diff whine
Same procedure for F83? And how do u know whether or not to replace driveshaft?
Yes. You don't need to replace your driveshaft when replacing the rear bushings.
@TunedAuto_Official subscribed to your YT and requesting to join your F8X owners FB group. I think I need to replace the bushings but have another primary issue in diff or driveshaft. . .or Trans 🤦🏾♂️
I have some questions as I want to attempt. What's the best way to chat with you? I need some assistance on this topic

@@tuned_auto requested
Hi. Could you share me the information on the bushing removal tool ??
There is a whole kit for the job: amzn.to/45bY65O
do mine!
hey what wheels setup are u running?
Rohana RFX5 20x10 et22 and 20x11 et28. I wish I did 9" in the front
you couldve just kept the driveshaft in and pressed out the bushings inside the car?
Technically yes but I didn't want to risk scratching up the driveshaft.
I have new ones installed 95 durameter polyurethane. Lots of Noise, vibration, and harshness. Hate it.
ECS tuning bushings?
@@tuned_auto yep!
@@tuned_auto the red ones
have had the same stupid red ecs bushings on my f82.. Makes my car sound like utter shit lol.. My wife makes fun of it saying it sounds like my cars messed up lol
@@GomesFPS negative… only way is to go back to OEM. 2018 LCI came with Poly bushings but I believe they have a rubber core. So I’d get those. Can’t really do anything if you have the red ones installed. I got used to it. At least they won’t go bad for a long long time.
I'm paying the dealer $$$$ to do this...as we speak 🫣
