How to: Change front Anti-roll bar bushes on MGF

Images courtesy of the-t-bar.com

Difficulty: 1 (even a monkey could do it)
Timescale: Assuming bolts are not seized, 30 minutes maximum

Yes, I am back, etc, blah blah , meh etc

To be honest, I never really checked these on my previous F. They are kind of tucked away and you never really hear of people having to change them. I replaced with all new parts but of course you probably don't have to do this (bolts/brackets)

(I might point out that this was done in the rain, and after 5 pints of beer, but I don't condone ANY car work whilst under the influence of alcohol. this is dangerous!!!)

Anyway, I decided to change mine for polyurethane, as they don't cost that much (around 20 pounds for two bushes)

Its a VERY easy job if the bolts come away first time.

Tools/parts required

  • 10 mm socket
  • Torque wrench
  • Car jack/axle stands or even better, car ramp
  • bushes - Rubber OEM- part no. RGX000920 (7.20 exc vat) , or patent part : RGX000920P (1.25 ex VAT) or polyurethane part no. SGF400032 (Sussex car parts - 24 ex vat)


Usual stuff for removing road wheels (locking key, 19mm socket, wheel nut wrench or torque wrench)


not essential but may come in handy:
  • impact wrench for initial cracking of bolt
  • New brackets (x2) (part number:RBU100101 (Rimmers, 7.40 each exc VAT)
  • New bolts (x4) (part number: KYP10002L 0.42 each ex VAT, Rimmers
  • Swear box....(if bolts don't come out)




1) Raise front in the air on ramps, or jack up and SUPPORT ON AXLE STANDS (need to do both sides at same time)

If on ramps then both wheels are under load and this should take stress of the roll bar. If you are jacking car, then I am not sure what effect this will have on the ARB as the wheels will be "hanging down" more than if on ramps......

Soak the bolts in plus gas, (WD40 if you have to) or other releasing agents.....day before would be better and you can just manage to do this with car on the ground





2) You can then get under the front of car and see the anti-roll bar and the bushes/brackets







(yes the subframe has been waxoyled since then)


3) Using a 10mm socket, remove the two bolts securing each bush bracket. I used an impact wrench to give the first "crack" as I usually strip bolt when I use a normal socket set. the seemed to come off reasonable easily and I sprayed whit release agent a few times during removal just to help. they are only torqued to 22 Nm so should come off OK, but do get rusty under there





4) Once bolts are out, the bracket can be removed and the bush removed from the roll bar. There is a slit in the bush to allow it to slide off the bar. Or in my case, they just fell off

5) repeat for bush at other side of car

6) New bushes came with some coppergrease, but if you are fitting rubber, then just use some long lasting grease or coppergrease in the bush to help it go on and to prevent squeaking in future. Slip on new bush and then fit the bracket loosely by applying the bolts a few turns (you can tighten them once both bushes are in place as you need to lower the bar slightly to get the new bushes on)





7) Now tighten up bolts to 22 Nm. It doesn't feel like a lot at all, but that's what the manual says :-?





Points of caution.

Obviously the hardest part is getting the bolts off in the first place.
The brackets on mine had been crushed (probably by someone using them as jacking points). This had also bent the part on the car that the bracket bolts onto, so the bolts couldn't go in straight, but they did go in with a bit of effort. I am hoping by using polys, I wont have to remove them ever again.....but I used new bolts and brackets so they might come off easily in future?

I'll post a seperate how to on doing the drop links that attach to the ARB. That was a pain in the ass for what should have been a 10-15 minute job ....more to follow

Nothing major, but notice it when going over speed humps and pot holes. Steering feels a bit better too. The old bushes were totally shot!

Well Done!
Mine was the opposite. The drop links almost changed themselves but the bolts holding the ARB brackets in place are so rusty I know they would shear if I so much as touch them. I'm saving them for a day when I feel motivated enough to drag out the torches and heat them up before having a go at them. I'm also out of beer.

you might be lucky. The bolts stick out the top of the bracket and only a short portion of bolt is in contact with the bracket, so you can s;pray release oil on the top part and it well run down and soak in..........hopefully
