Revolution Posted February 11, 2014 Report Share Posted February 11, 2014 Hello Everyone I'm looking to replace the rear, rubber suspension bushes with polybushes Is it necessary to dismantle the whole of the rear suspension to do this or can the weight of the rear spring be supported by a trolley jack and the bushes replaced with the trailing arm in situ? Any advice greatly received Nick Quote Link to post Share on other sites
TRseks Posted February 11, 2014 Report Share Posted February 11, 2014 (edited) I have heard that it is possible to do this without removing the trailing arm, but I can`t imagine it to be easy... I did this on my TR6 and removed "everything", not a lot of work really, and you get the opportunity to clean and check everything properly.

RogerH Posted February 11, 2014 Report Share Posted February 11, 2014 Hi Nick, remove the TA, it is not a great deal of work and then all the bits can be looked at/inspected. Remove the brackets that hold the TA and check for cracks coming out of the attaching bolt holes - they do crack; how do I know this!! Roger Quote Link to post Share on other sites
Revolution Posted February 12, 2014 Author Report Share Posted February 12, 2014 Thanks for your help guys....will strip the lot down.....don't want any cracks in my brackets.......sounds painful !! Quote Link to post Share on other sites
AndrewMAshton Posted February 15, 2014 Report Share Posted February 15, 2014 Hi, when you come to put the whole lot back together again make sure you put a plates on the bolts holding the brackets to the chassis between the chassis and the two nuts, this will help spread the load, the alternative is the nuts being pulled through the chassis and a large bill to get it fixed, if you think it wont happen I can send you some pics, and there isn't a bit of rust in sight! I am sure CTM supply the plates, Andrew Quote Link to post Share on other sites
peejay4A Posted February 15, 2014 Report Share Posted February 15, 2014 Aren't there supposed to be tubes for the bolts to go through between the chassis verticals to stop that happening? Quote Link to post Share on other sites
ctc77965o Posted February 15, 2014 Report Share Posted February 15, 2014 Aren't there supposed to be tubes for the bolts to go through between the chassis verticals to stop that happening? yes, there are tubes inside the chassis so the TA brackets don't crush the chassis Quote Link to post Share on other sites
AndrewMAshton Posted February 16, 2014 Report Share Posted February 16, 2014 Hello again, there are tubes, however in my case they didn't save the chassis, the chassis was about 10 years old, as you can see from the photographs, only surface rust, certainly no serious rusting, I think I ran over a pothole but what I can say is the car is not driven hard and is well looked after, I run on wires as well so thought they would absorb some of the shock. There were ordinary washers under the nuts and the diameter of the washers was the same as the weld on the tubes, so any force would be on the transition between weld and metal, I am not an expert but suspect it must have weakened the steel plate, hence the damage. It was fixed, at a huge cost, and I now have plates to spread the load, front as well! Quote Link to post Share on other sites
Revolution Posted February 16, 2014 Author Report Share Posted February 16, 2014 Thanks for the advice Andrew. Have checked carefully around the area where the brackets are bolted and all looks really solid...including the brackets. It's a bit worrying if that happened just with surface rust.....will consider strengthening with plates Cheers, Nick Quote Link to post Share on other sites
Guest ntc Posted February 16, 2014 Report Share Posted February 16, 2014 Nick You need not to remove the arms to change the bushes Quote Link to post Share on other sites
Revolution Posted February 19, 2014 Author Report Share Posted February 19, 2014 Neil Yes, I'm sure you are right but I would have struggled to remove the old rubber bushes with the arms in situ. Real struggle to remove the old inserts and bushes and had to set fire to them and then carefully drill the rubber away - all with the arms off All cleaned up now and ready to re assemble Regards, Nick Quote Link to post Share on other sites
peejay4A Posted February 19, 2014 Report Share Posted February 19, 2014 Nick, I have the proper tool to remove and replace the bushes. If you're stuck you can borrow it. Quote Link to post Share on other sites
Revolution Posted February 20, 2014 Author Report Share Posted February 20, 2014 Thanks for the offer Pete but have managed to remove the bushes ok and am replacing with polybush type Nick Quote Link to post Share on other sites
