98 S70 When should you replace your stabilizer bar?

Post by theWIFES_S70 »

Looking underneath the S70 and trying to figure out where some clunks are coming from. The car is now an absolute dream on the highway. But at slow speeds, the creaks and clunks abound... I found a tear in the transmission mount. (Oh Proparts!) Will DIY fix that this week and will install a new upper torque mount bushing. But I also saw this...

I've got tears in my stabilizer bar bushings. :o

What kind of "hesitation" and/or "clunks" would this cause? When do you know you have to, or should, replace your stabilizer bar? It sucks that you can't just replace the rubber. Is it possible to squirt Vulkem in there? Or is that an absolute hack way to tackle this? As always, many thanks for the insight everyone!

How do you mean you can't just replace the rubber?
That bushing is replaceable part.

I thought it was all one piece? Rubber that's vulcanized to the bar? Man, please tell this is easily replaceable like on Jeeps!!

It's not vulcanised to the bar!
It's easily replaceable part. ;)

Lower part of that bushing have the opening which serves to spread fit the bushing onto sway bar.

It looks like this:

Thanks Misha! I knew IPD made these pieces. But I know they only fit onto their stabilizer bars.

You have to drop the subframe for this job right? Or is there enough clearance to hit those bolts with a wrench???

I'm not really good at dropping the subframe... :?

I don't think that you would need to drop the subframe.

Whole front end in the air on jack stands to release the tension from sway bar and go for it.
If you have acces to a lift or channel it would be a lot easier.

You DO need to drop the subframe and this is not the way to go
Buy a set of IPD sway bars, it will be quiet and...the car will handle 100% better

Worn subframe bushings make the whole front end of the car feel like it's falling apart. My T5 was sold to a family member who owned it for several years before giving it back to me this summer. When I drove it home it felt like it needed every part in the front end and an alignment. I knew from experience however that I just needed to replace the ipd poly subframe bushings and when I did, everything tightened up and no alignment necessary.

I agree that the IPD bars are a great upgrade, but those poly inserts don't last long. I'd reckon they need to be replaced every 25k or so at least on the kind of roads we have around here.

Wow, that IPD kit is expensive... Sigh, I guess we'll just have to live with it for now. Thanks for the insight everyone.

You can still replace the bushings independent of getting the ipd kit. I would do that with a regular Volvo part.
