Hi MGTFnut, thanks for your response. I've done all the other (poly)bushes, I've been putting off doing the wishbones because of the additional subframe issues. I didn't use washing up liquid but KY Jelly!! It's water based and nice and slippery!! Yes, I've identified the front & rear and the fact t...

Thanks for your reply Gerry. Yes, they are MGF "Polybushes" as supplied by RimmerBros, orange colour with a steel tube insert to accept the 10mm securing bolts. As I said, I think the 2 biggest bushes go to the rear of the wishbones, the smaller ones to the front. I still don't know which way to pre...

I now want to fit polybushes to the front lower arms (wishbones). Each new bush has a thick flange and a thin one. Does it matter which way they are fitted? The 2 biggest bushes go to the rear, and the smaller ones to the front of each wishbone. I think that (looking from above), at the front, the b...

Sadly, I've decided to get rid of my 2001 F. It's just suffered the 3rd HGF in 6 years. I've taken all the precautions, steel dowels, QED remote thermostat mod, MLS gasket, strengthened oil rail, etc etc. It's just too unreliable and I'm sick of throwing money at it.

This is the method I used, the pic shows removal of the F tie-bar eye bush. It worked a treat on all the F rear bushes, but the tie bar to chassis bolt is a pig to get at - it's too tight for a 1/2in drive socket, it's got to be a 3/8in drive 13mm socket.

Hi Beefio. I'm halfway through fitting a full set of polybushes to my F, Upon removing the first lower (rear) arm, out popped a little L shaped bracket between the bolt end (the one that's accessed from a slot in the sub-frame) and the inner bush. It looks like a spacer - it doesn't appear in the WS...

Polybush fitting - an update for anyone considering a DIY job. A couple of tips - Ben Finlayson did a great account on the MG-Rover forum back in 2010; it was very useful but a couple of comments on his and my experience so far. The tie-bar to chassis/subframe bolt is hidden inside a bracket, part o...

Well the suplex conversion is done and so far I'm very happy with the result. I know the reviews have been mixed, but from what I've read the views are mixed. Anyway, next stop Polybushes - I read an excellent account on TBar on F rear bushes, but the author didn't mention ARB bushes; that's where I...

Hi, enjoyed reading this string. My spheres were shot, the car was down on the bones of it's arse. Here in Cyprus there is no way to get them re-gassed or even fluid re-pressured; I suspect the membranes in the spheres had failed. So I went for the Suplex solution, did it myself no real problems apa...

BTW, the numbered comments above refer to the Suplex supplied instructions which can also be downloaded from the Rimmer Bros website

Here goes with my DIY Suplex Installation experiences. Hope it helps: Can I share with you my experience with a DIY Suplex installation, which hopefully you may find useful: The first wheel to be removed had one wheel nut (reamed on far too tight by some clown at a local tyre dealer). I destroyed 2 ...

Thanks for the replies, it's all sorted to the approved ride height. As you say, 368mm does look high (Landrover or pickup truck)!! But Cyprus roads are terrible with lots of speed humps so I'll live with it. Meanwhile I'm thinking of a big post with my experience of a DIY Suplex installation, hopef...

Hi Joe-MG. I'm in Cyprus and have just finished the Suplex conversion. I'm ready to adjust the ride height, but I'm confused by the number of variables; MG Rover say 368mm front, 363mm rear. But I guess that's based on the Rover tyre recommendation of 215/40 tyres all round, correctly inflated. I've...

I've finally finished the Suplex conversion. I could write a book about the issues involved but none insurmountable. I have one remaining problem: Upon measuring the ride heights (should be nominally 368mm F, 363mm R), the car looks like a pickup, with huge gaps between wheel arch and tyre. But the ...

I finally managed to remove the rear NS sphere. What a pig, but once I prised the knuckle up and out of the suspension arm it was a doddle. Now I'm having a problem getting the knuckle back in place. It's supposed to be a "push fit"!! You'd need muscles like Popeye to push it back into place. The pl...

I'm halfway through the Suplex spring conversion and I can't get the old knackered rear sphere up & off the piston/knuckle. There is just not enough room. What a pig of a job; I've had to drill out or cut off half the various nus n bolts. Any suggestions?

After 2 catastrophic HGF's I took a lot of good advice on this and other forums: new cylinder head, strengthened bottom oil rail, MLS gasket, SS coolant pipes and QED thermostat location mod. Already had steel locating pegs. Expensive, but hopefully (6000 miles later), all's well. Next problem is re...

One more question - the workshop manual only mentions ride height on the front wheels. Is it reasonable to assume the rear wheels should be the same (nominal 368mm)?

Great, thanks
