Looking from the side it was below the rear axle. I haven't been under the car to inspect it - as the years go by it's getting rather challenging! Quote Link to post Share on other sites
BusheyTrader Posted September 13, 2021 Report Share Posted September 13, 2021 Rear bump stop. Much like the front ones they fall apart from about 30 years old. Poly ones are available if you don’t want to replace them in another 30. I can’t remember the rear axle touching them, unlike the front ones….. Quote Link to post Share on other sites
john.r.davies Posted September 14, 2021 Report Share Posted September 14, 2021 There it is! Top right. But what holds it in place? Just friction on a peg in the hole? Quote Link to post Share on other sites
BusheyTrader Posted September 15, 2021 Report Share Posted September 15, 2021 There’s a moulded stalk at the top end. It’s a push fit and a recess stops it falling down, which it does when it disintegrates. https://www.angclassiccarparts.co.uk/products/triumph-5981/tr7-tr8/suspension/rear-chassis-bump-stop-tr7-tr8 Quote Link to post Share on other sites

Chris59 Posted September 15, 2021 Report Share Posted September 15, 2021 It's doable to change these bump stop with the car on the ground, it can even be done without removing the wheels. Quote Link to post Share on other sites
acaie Posted October 11, 2021 Author Report Share Posted October 11, 2021 Thanks to all, and in particular to dursleyman for his advice on how to fit new ones. Potentially one of those infuriating jobs which sound easy and then take hours and lots of bad language to achieve what should be straightforward. Using dursleyman's technique it was 30 minutes on the right hand side and 20 minutes on the left. Al Quote Link to post Share on other sites
Propshaft Posted October 12, 2021 Report Share Posted October 12, 2021 What is dursleymans technique Quote Link to post Share on other sites
acaie Posted October 13, 2021 Author Report Share Posted October 13, 2021 The rubber end has to be pressed up into the chassis but is a tight fit so plenty of fairy liquid lubricant and a jubilee clip to squeeze it. Then put the rear on stands so the axle can drop. Cut a piece of wood to fit as shown and jack up the axle to get the rubber started into the hole. Once it is fully engaged you can take the jubilee clip off and push it completely in. With thanks again to dursleyman Quote Link to post Share on other sites
john.r.davies Posted October 13, 2021 Report Share Posted October 13, 2021 Fairey Liquid is said to contain enough salt to cause local corrosion. Rubber grease might be better. John Quote Link to post Share on other sites
