JKJ Posted December 5, 2001 Share Posted December 5, 2001 Just wondering if any of you guys could tell me how easy it is to renew the A-frame bushes, and more importantly how to do it. The said item appears to have degraded, with part of the exposed bush splitting, no obvious affect on the handling, and the rear end seems quite stable. Thanks in advance.

Baby Bucket Posted December 7, 2001 Share Posted December 7, 2001 Very easy, There are various threads on here. But as a summary, 1. Jack up the car and support where the A frame joins the chassis using axle stands. 2. Remove bolt from A frame bush and pull down A frame. 3. Remove old bush and check to see whether there is a washer between the two halves of the bushes - some do, some don't. 4. Insert new bush - USE NO OIL or GREASE!!!!. It help to squeeze the two halves together using mole grips or G-clamp. 5. Push A frame back into locating lug and replace bolt. Cheers Peter PS Oil & grease is what causes the bush to degrade in the first place. Link to comment Share on other sites More sharing options...
Rod Thonger Posted December 8, 2001 Share Posted December 8, 2001 Thanks for that, Peter. I can remember having a hell of a problem getting new bushes inserted in the past. However, this business of oil/grease, and split casings, old 7 problem. Mine's dripping a bit, despite strengthening. Why hasn't this problem been solved????

AndreK Posted December 8, 2001 Share Posted December 8, 2001 A little lubrication with washing up liquid may help, particularly if cold. Also warming bush in house may be worthwhile Link to comment Share on other sites More sharing options...
tony isherwood Posted December 10, 2001 Share Posted December 10, 2001 I was thinking of doing a rearend overhall (ooer) this winter, generally how much of a job is it to remove all the bushes ? In particular I am thinking of the rear arms which connect under the mudguard to the axel. Do they size ? nothing has been done to them for at leat 4 years? (10 thou miles). Probably the originals In which case nealy 7 years. Am I looking a loda grief ? Link to comment Share on other sites More sharing options...
Jam Mad Posted December 10, 2001 Share Posted December 10, 2001 jkj, i did this with a friend of mine earlier this year for the first time... it's a bit fiddly, but easier than i thought. all in, it took easily under an hour. the key to success was a pack of red budget g-clamps from b&q. they come in three sizes, and the smallest one ( i think ) was extremely useful to compress the bushes before pushing it all back together again. there is a lubricating paste that you can apply to rubber ( not copperslip, i've forgotten what it's called ) that helped a bit. have fun ! it's an essential baptism of seven tinkering. see ya', j Link to comment Share on other sites More sharing options...
Dave H Posted December 10, 2001 Share Posted December 10, 2001 Tony, The Bushes can get siezed in place, as can the bolts that hold it together. I had to resort to a large club hammer, hacksaw, and finally the big press at the local garage to remove all the bushes from the back of mine when I did the rebuild this year (first time in 14 years some of them had been removed). if it was assembled properly, with plently of the right sort of lubricant, and its not been out in the wrong conditions (salty roads esp.) you may be OK.

Super_Rich_Bernie Posted December 10, 2001 Share Posted December 10, 2001 The special friendly to rubber and non-corrosive lubricant is available in a tube from your local pharmacy. Just ask for something to ease insertion.... A couple of strips of aluminium and some G-clamps help too. Jonathan Link to comment Share on other sites More sharing options...
Alex Wong1697456877 Posted December 10, 2001 Share Posted December 10, 2001 I removed all the bushes from front and rear suspension over the weekend. You really need a press to remove them, although Roger's made a tool involving a recieving "cup" and a big bolt which makes getting the A-frame bush out easier. They so seize into place and require alot of force to get out. Alex Link to comment Share on other sites More sharing options...

warrent Posted December 11, 2001 Share Posted December 11, 2001 Jonathan, Whats the lubricant called, that you get from you pharmacy. Does it really help getting in tight bushes?? Link to comment Share on other sites More sharing options...
Graham Sewell Posted December 12, 2001 Share Posted December 12, 2001 I assume it is called KY jelly - apparently it has uses other tban putting A-frame bushes together but I wouldn't know about that. Otherwise, H*lfrauds sell a product called Holts Rubber & Nylon Lubricant. Link to comment Share on other sites More sharing options...
Super_Rich_Bernie Posted December 12, 2001 Share Posted December 12, 2001 A 'Super 7' should be OK with all but the tightest of bushes using the prescribed lubricant or Halfords equivalent Rubber & Leather lube. Those who talk of needing special tools, presses and lump hammers are possibly boasting..... J Link to comment Share on other sites More sharing options...

Alex Wong1697456877 Posted December 13, 2001 Share Posted December 13, 2001 JonathanG, There are 2 types of A frame bush. The older kind (2 bushes) is easy to get out. The newer kind (single metal sleeved bush) is a pig to get out and needs a press, special tool or a lump hammer. smile.gif Alex Link to comment Share on other sites More sharing options...
edmandsd Posted December 14, 2001 Share Posted December 14, 2001 When you start putting reasonable power through a live axle, or even drive a standard live axle car hard for that matter, the A frame bushes last 5 minutes and the diff nose leaks. HT Racing have solved both of these problems and now have several satisfied Caterham owners with box section strengthened English axle replacements at reasonable cost. They are designed to be direct replacements for the Ital giving strength, light weight and a wider choice of cwp's with lsd provision. In addition they don't need your axle and are returned fully powder coated. Telephone Aaron Tucker at HT Racing for more details on 01474 872888.
