Rear spring isolators

Blink · 21st June 2019, 12:50

Has anyone bothered to replace the rubber isolators when fitting new rear springs? They seem fairly bullet-proof to me so I'm not sure it's worth the £50-ish.

The spring I got from Rimmers a few months ago had them already on the spring. But I'm going to be cleaning the old ones and reusing them on future springs.
Only problem is they're a bit of a mare to get off. Especially when the spring breaks leaving about four inches still attached. Plenty of washing up liquid and a sturdy screwdriver and the bits eventually come out

It's odd that some of them come with isolators and some don't .

Mine (RKB101420 / RB / Pink) isn't even listed on Rimmers now so I've bought a pair of KYB's instead. I'll wait & see if I can get the old isolators off without wrecking them before I buy new ones.

I think the original MGR springs tended to snap because of the way they were cut - i.e. tapered instead of 90 degrees.

The rear springs sometimes snap due to poor fitting of the isolators, blocking the water ways on the rear arms causing water to collect and rot the rear arms, you will find they tend to snap at the very bottom at the tip where the water has collected and caused the protective coating to come away

I refit the old ones which were still supple and intact as my car is low mileage. As Mickey says, just make sure that the slots line up with the drain holes when refitting or you will get pooling, resulting in premature tinworm on the arms.

I re used my old ones as there were no new to be had except from Rimmers on certain spring configurations............unfortunately not the right ones for my car. There were a couple of second hand ones on ebay but looked no better than the ones I took off.

Used marinabrians method of replacement which was really easy and allowed cleaning and painting / rust proofing of all the subframe assembly.

As has been said, watch those drain holes.
