Suspension: - Delta link bush replacement - new bolts - Page 3

Did mine again (last about 6 years, 120k) end of last year, utter pig as the inner bush socket were likely original and never been changed, both had a small amount of play, really tiny, but the issue was the bolt that goes through was galvonically corroded into the bush and delta arm so impossible to adjust that side of the car. 2 hours of cutting, prizing and heating and beating to get it out without scarring the alloy delta arms. Did it but hell of a job.
Use anti seize grease on all dissimilar metals people. And new bolts, or at least not 25 year old 300-500k old bolts, death awaits those who don't use common sense*

*There are times where reuse of a bolt is fine. But on this job for the £2 a bolt for a nice shiny new one, really worth not changing?

A couple of posts have mentioned the alloy arms. Now I know there are differences between S/V and C70, namely solid mounts in the front subframe instead of squishy ones and a wider rear track on the C. The delta arms on my C70 are galvanised steel, did the S/V really have alloy arms?

Not that I'm aware of, all galvanised steel used here to the best of my knowledge, only difference here being the wider links/arms on the C70 as you correctly say.

Perhaps some confusion with regards to the early 850 (alter 1) which had the alloy front lower control arms? These also had removable ball joints which you see listed on various parts sites.

My mistake.

On a 1999 V70 FWD (and presumably other similar V70s and C70s) the trailing arms (where the splined bolt goes) are steel (just tested with a magnet), not aluminium.

Don't know where I got that idea from.

An easy mistake - we all do it at times. It was just that two posters mentioned alloy so got me wondering as I am not familiar with the S/V's.

This is enlightening - judging by the appearance I'd always thought that they were aluminium too, but you're right - actually galvanised steel makes more sense from a strength (and cost!) point of view.

Doesn't stop that splined bolt being a sod to get out though eh?

Hi,

Had a go at removing the delta link bushes on mine today, managed to get the three smaller bolts out of support bracket also the longer bolt which runs through the bush its self and the smaller splined one out, i can not seem to get the delta link bush end off the car ( help) i am guessing this needs a good prying?
i have managed to get the three smaller bolts from our local nut and bolt place, but he said he could not find a replacement for the longer one, can anyone confirm that the bolts holding the delta link bush are 977509 ( longer bolt) and 987341 for the splined one.

Cheers Craig

Yes, those are the correct part numbers.

My old bush came out without too much difficulty with the aid of heat and careful use of the puller tool. The hardest part for me was shifting the splined bolt.

Is it easy enough to get the new bushes in?

Martin Cox · May 18th, 2023, 19:19

I didn't have any great difficulty but I did have the advantage of having the Volvo tool for the job.

The key to it seems to be the following:

Make sure the socket into which the bush fits is as clean as possible.

A little silicone or other suitable grease on the plastic part of the bush will help.

Make sure you get it the right way up!

Push on the metal part of the bush somehow to drive it into the socket trying to keep it straight. Some folk just hammer them in. It will probably go in in fits and starts and you may end up having to 'walk' it in from side to side slightly.

It's fully home when you can get the splined bolt through to keep it in place.

Hope this is of some help

Martin.
