I could not find a
lot of info regarding the fitting of a beam axle so thought it best to speak to
someone direct. So on Monday 9th Feb I phoned Huddersfield Spares as they
manufacture a beam axle for the mini I thought it best to speak to them
direct. After speaking to Andrew who answered my question I decided to order
the beam axle plus shocks on line that evening (8.17pm). Total cost was
£311.50 including the rear handbrake cable that also needed for the
MOT.
Tuesday 10th Feb (9.07am) I got an email telling me the shipping
would be £20 making a total of £331.50 At 4.41pm I got the email
telling me my order has been dispatched. |

|
Wednesday 11th Feb 12.20pm beam
axle arrived with shocks and handbrake cable. |
|
|
|
Subframe was off in
about 2 hours and the underneath of the mini was then cleaned and the beam axle
offered up to the mounting holes, I did not expect it to line up correctly and
I was right, there was one hole that did not line up (see
photo).
This was not
a big problem as it was not much out of alignment I drilled the hole to
suit. |
|
 |
| |
|
|
| I marked the other two holes for
drilling before applying underseal. |
 |
|
 |
| |
|
|
| The knuckles on the swinging arms
have to be cut off as they hit the bottom of the beam axle. This was done with
a thin cutting disc on an angle grinder and then ground down smooth. This went
without any problems. |
 |
|
 |
  |
|
 |
| |
|
|
| The tops of the beam
axle were rounded as it was a tight fit as some welding had been done to my
car.
|
|
 |
| |
|
|
| Beam axle
fitted. |
|
 |
| |
|
|
The first thing was to
fit the break union and pipes, we found the bolt in the beam axle
was: 1) Not long enough to go through the
union. 2) It was in the wrong place (at least for
my mini). |
|
 |
| |
|
|
| This was a simple
thing to fix, a simple bracket was all that was needed. |
|
 |
| |
|
|
Fitting the brake pipes, the
drivers side was to short and a new pipe had to be made about 3 to 4" longer
than the original pipe The left side was a bit
long so was shaped to run along the body and did fit OK. |
 |
|
 |
| |
|
|
| Putting the plates on the swinging
arms we found that the holes were not big enough to go over the pins. By
scraping of the powder coating they fitted OK. |
 |
|
 |
| |
|
|
With the swinging arms and the
shocks on we found the shock springs were hitting the inner
wheel arches both at the bottom and at the top.
Simply widen the top out at the sides and bend
back at the bottom to make room for the shocks again not a big problem and easy
to fix. |
 |
|
 |
| |
|
|
Once we had clearance for the
shocks and everything in place it was time to set the camber. We set it up to
have some negative camber only to find that the wheels on the tyres were
hitting the springs.
Backing off the camber fixed this problem (this again will depend
on your own minis wheels & tyres).. |
 |
|
 |
| |
|
|
| Time to put the
exhaust on, we made a rear bracket with an exhaust bobbin bolted through the
boot floor and a bracket (most of this was from parts that came of
earlier). |
|
 |
| |
|
|
| Photo of middle
exhaust mount. This was made from bits we had lying around and bits that came
of earlier. |
|
 |
| |
|
|
| After we bled the
brakes and made sure all was tight the wheels went on and we lowered the car to
the ground and that was it finished (or so we thought). |
|
 |
| |
|
|
We went to move the
car and the wheels were rubbing against the shocks (again). They were fine when
the car was jacked up but not when on the ground.
I phoned Andrew at Huddersfield spares about this and he said
it was the standard 4.5J Rover wheels I have on the car, the off-set was not a
lot on these wheels and that is why they rub the shock springs. I had three options:
1) Use less negative camber as this
would take the tyre away from the springs. 2) Fit
spacers. 3) |Fit wheels with a greater
off-set.
I went to my local motor factors and got a pair of
universal 5mm wheel spacers. I could not go any thicker as I did not have
longer wheel studs. After fitting the spacers the
wheels cleared (just) and of I went on the first trip with the new beam axle
fitted. |

Did the beam axle make a difference?
YES IT DID. The road holding was far better and
the car seamed well planted on the ground and turned into corners very nicely
with a lot less leaning and tail sway.
Was it
worth all the work? YES IT WAS.
Would I do it again? YES I WOULD.
but not from Huddersfield Spares
Would I recommend it? YES I
WOULD. but not from Huddersfield Spares
Would I like to see any changes made? YES I WOULD. An instruction leaflet including the issue with
standard cooper wheels, the holes the spindle from the swinging arms go through
should be just a little bit bigger to allow for the powder
coating. A longer brake pipe, bracket for the
brake union and exhaust mounts could be supplied with beam axle making it a
bolt on unit. |

|
|
| These are early days
and I will see how things go after a few weeks driving. |

|
| BIG thanks to Scott
and Mike from New Bridge Garage who without them I would have had to do the
job on the street as Mike let me use his garage space and Scott done most of
the work while I took the photos, went for the pasties and parts
needed. |

| Mini passed its MOT today 23rd Feb 2009 |

It is now the 11th March and all is
going well with no problems so far. I did a 300+ mile trip on Sunday going to
the Malvern show and the trip was mostly on motorway with a few B roads that
were quite uneven and the beam axle held up very well. Some have told me that
it is meant to not handle well, all I can say is it does on my mini and I would
not go back to a subframe even if it was free and fitted for me. |

It has
been a few months now and the beam axle is still holding up. I had this
squeeking going on at the back and it was getting on my bits, so I stripped out
the shocks and copper greased the bushes etc. and that got rid of most. I still
had the petrol tank squeeking so out it came and painted then back in. Still
squeeking, out it came again and found the shock tops were to long and hitting
the tank. Put some washers on the bottom bush to pull the top of the shock down
and no more sqeeky tank. I will have to ask about this to see if it is just my
car but I think I will put polly bushes on. I can lift the back wheel arch and
lift the rear wheel of the floor so it is a bit lighter now. |

This is
now really getting me down. I still have the squeek. The petrol tank has been
out so many times its not real. I have changed the back wheels and re-done the
shock mounts etc. and the squeek goes till you hammer round a few corners and
then it comes back. I am sure it is the top mounts. I contacted GAZ and they
have said they will have a look at the mini to see if they can fix the problem.
I dont know if I could handle 41 days of the squeek. The performance is great
and so is the ride but the SQUEEK!!! drives me nuts. |
