How to: Replacing suspension bushes (rear) on MGF-the easy way

Needed to replace bushes on my shock absorbers (dampers). I know they ar enot polys, but for 1.60 each, if they last another 8 years, then I am not complaining

Looked at excellent how to on Rob Bells site. This involved removing dampers. Not a problem...on paper. Couldnt get a good enough grip on top part of the shock to remove top bolt.

So I thought...do I need to remove damper...

No I didn't. Thought it was just easy cos my bush was so knackered, but on the other side, the bush was in better condition and I still did it without removing anything on car, just 1 bolt

So , I will skip obvious stuff such as removing wheels and using axle stands for safety, as this is obvious.

Here is the shock absorber with bush at bottom. This was easily moveable with my fingers...bad times..



This bolt is 17mm, not 14 as mentioned on Rob Bells site. However most sockets wont fit over the bolt, so you need a deep socket. I had a double ender I use to remove wheel nuts, 17 on one side, 19 on the other (19 for the wheel nuts), and this worked a treat. You need to hold the nut at the other side with a socket/wrench or an adjustable wrench.



Caution though the bolt on the bush side was well rusted on and this happened to my first 13mm socket. Found a HF Pro one which is good quality and that did the job. You may also want to lube the end of the bolt with release oil for 5 mins or so as this is very rusty and its hard to get the nut off the last bit.



Anyway, when nut comes off, remove the bolt, a spacer and 2 washers will fall out. The washer goes against bush, the spacer against suspension parts.



The first bush just pushed out by hand, as did the central metal tube (can't think of a good name just now). The other side was in better nick though and in order to get metal tube out I had to use mole grips and a small socket with tapered end. Pushed the small end into tube then presses it through with moles grips.



Next the bush, again much tighter this time. Used a screwdriver and it was easy enough to persuade out.



Here is old bush (worn) and new one. Cost, 1.60 from Rimmers




To replace, this is where a vice comes in handy. Not ideal if you are doing it on the car, but my vice was small enough to do the job, I reckon it would also be possible just using mole grips etc.



Anyway lube up the rubber , I used white lithium grease, dunno if thats OK or not. I assume it wont perish the rubber though. The bush simply presses in by hand.

I then used the vice to insert the metal tube into the bush. Finished it off using mole grips.

Or another tip here

Now, in true Haynes fashion, fit in reverse

The nearside one had an extra bracket which attaches to a cable to the brakes. This remains attached though, so its difficult to not remember to connect it.




Whilst wheel was off I changed my chavvy red rear calipers to silver, to match the front. Bit less "show off" than red, but better than rusty metal.

Yeah. My car has been jumping around at the rear when going over vbumps, very twitchy, and generally bumpy. I noticed a few months back that the damper simpy moved with little pressure, so I knew it was a gonner. Its quite a common feature on Fs due to their age and the fact its a rubber component. Add to that the state of the roads in Aberdeen I already had to change the tie rod bar thingmy last year too, due to perished rubber. I dont think it helps that my suspension is needing pumped and has done for several years

I went for a drive tonight and its quite a startling difference in ride quality!! Going for a decent windy road trip tomorrow should be able to confirm.

Unhappy Anti roll bar links

Just changed the anti roll bar links as they were perished.Changed me wheels as they had a wobble on the front.Difficult to balance.Changed the brake caliper as was seized but still av a bit of a wobble somewheres.Seems to be a bit shaky everytime yer hit a slight bit of rough road.Whilst doin the roll bar links,had a look at the damper bush.Moves around quite a bit so guess it may be gone.Noticed that the offside disc may be slightly warped as well,so this may be the prob......

Nice idea getting the vice to put the bush on with - these can be a real struggle to fit - they were on the Morris anyway - it took 2 of us to get the bushes in place

Mmm,
I honestly don't know. Looking at them on the car, I assumed they were all the same, but seeing the different part numbers make you think. Having said that, Mike Satur sells a poly set and all four corners look identical; as do his shocker set.
It looks as if you'll have to tell us when you get them!
