Live Axle Trailing Arm Rubbing
Avoneer - 4/9/07 at 09:15 PM

Has anyone else experienced some tyre rubbage on the front 2 bolts that hold on the trailing arms?

It's just that I've never seen it mentioned on here, but it may be more common than just my car.

Didn't really notice it on the road on mine, but knackered a tyre at Elvington on Saturday because of this.

As commented in the other thread, put me on the list of having suffered this

That's with 205/60-13" tyres, needed a 5mm spacer on each side to resolve it, or wider rims.

Yup I need 10mm spacers. Running 195 50 15" tyres.

Yes it's a common problem. I used 10mm spacers as otherwise my 185/70 13 tyres just touch the bolt heads. I could have used thinner but they also set the wheel in the arch nicely.

Me to 5mm spacer on 13" rims with acb10's and 5mm spacer on Peugeot offset 15" rims with 195 50 15" tyres.

Although the 15's rub on the outer edge of the arches with DavidM as a passenger!

Hi are the tyres rubbing on just the arms or the mounting bolts at the front.

How short/long are the arms bolt crs.

cheers matt

Hi Matt

Its on the head of the bolts themselves that protrude a bit too far into the wheelarch area and catch on the edge of the tyre, the ones that locate the trailing arms to the chassis.


As mentioned in the other thread, you can get M12 button head bolts which may have a lower head profile which may help.

Hi its alright. Most of you must be running short arms as 13" arms putt the bolts past the tyres reach.

cheers matt

Yep - 12" arms and it's rubbing on the bolt heads and a little on the bracket - but my tires were at 16psi and we we weren't going slow on the corners with two in.

Cheers all.

10mm spacers and better bushes for me!

Why would he want to downgrade Phil?

So he doesn't shred his tyres...............

Other than that


MikeR - 6/9/07 at 11:30 PM

but if we convert to IRS then we'll have extra weight at the back of our cars & if we're not careful our 13" wheels won't fit.

Simpler answer, 'downgrade' to 14" wheels.


Avoneer - 7/9/07 at 07:26 AM

Or fit wheel spacers and less grippy tyres!

I'm happy as I am thanks.

Oh, and my rear axel, 3.54 diff and all associated parts came to less than £50.

Try and beat that with IRS, Diff, shafts etc.
