Rear subframe bolt protector
« on: July 19, 2012, 02:35:21 PM »
Finally did a little job on MM that i have been meaning to for awhile.

Rear Subframe Bolt protector.
Following is an easy job to do that could one day save your rear tyre. Rear Trailing arms on Mokes have been known to fail on occasion, when this happens the rear wheel moves backwards and inwards. The rear subframe bolt is perfectly positioned to meet the sidewall of your tyre when this happens. Depending on how quickly you pull up will be the factor on how much damage this bolt does to your tyre. The first step is to trim the bolt back so it is only one or two threads proud of the nut, this increases the surface area of impact, if you choose to do nothing else.
An additional safety measure is to fit a Protector tube. I have come across this solution elsewhere so thought I should share, and another option to the one on Mokewerx.
You require 100mm (4”) of 50mm(2”) x 20mm(3/4”) RHS Tubing. DO NOT USE 25mm . Wall thickness not important, what ever you can get your hands on.


This will be cut in half to make two protectors but easier to hold at this length while drilling the holes.
The holes are positioned 25mm in from each end and the side. On one side will be 2off x  25mm hole and the other side 2off x ½” holes. If you don’t have a 25mm Drill then a hole-saw will do the trick. If using a Hole-saw do the 25mm hole first because the Hole-saw pilot hole will then go through the other side and make drilling the 1/2” hole easier. Drill the 1/2" holes. Then just cut the piece of tube in two halves


The 25mm hole is so that a 11/16” Socket can fit through, which is what you need to undo the subframe bolt nut. It is now just a simple matter of fitting.
You will need to jack the car up and remove road wheel. Use car stand before working under vehicle. Remove the Subframe nut and large washer.


Then just fit the Protector Tube, then the Large washer inside the tube, and the nut.


Tighten up the nut. Once you have refitted the road wheel check that you have clearance between the tyre and protector tube.


Job done.

pink is always a nice colour to paint them,  ;D

Nice one Pete.

I've looked at various protectors over the years and tried a few, some were better than others.

I like that one and will probably use that on my current build.

Keep them ideas rolling in  ;)

Very neat Mr Pete! I will have to make a couple for mine. Nice write up too, thanks. ;)

You mention not using 25mm tube - is that because it's too close to the tyre?

Thanks all as i mentioned it was not my idea just a little refined ;)
Yep, Oh Great Rabid one, not enough clearance, which is a pain as everyone has a bit of offcut fence rail hanging around!! :-\
Wondered if you would spot the "pink" comment Mav. always on the ball..  ;D

Exactly! That's why I asked.... ;)

I'd best have a good look on the scrap heap then - bit of a waste cutting 100mm off a 6m length.... :o

Thanks Pete.
