XC70 Subframe

[SignumGB]

Hello,

Does anyone know if the subframe is generic? Ie those that fit on diesel models will fit on petrol?

Also, what sort of price would you expect to pay for a new subframe?


Thanks

Got underneath and took some images. Would anyone bother replacing this or just leave it as is? It is worse for not horrendous, but it was something a garage highlighted.

It’s holed near a mounting point or damaged near the gearbox mount? I don’t think that would pass test here in the UK. It’s certainly looks crusty.

Salt use must be heavy where you are so chances of finding a good second hand one might be slim? You might end up having to buy new. I would be looking at protecting the rest of the car with something like fluid film to help prevent any further issues.

I was asking myself the same... But, mine was only some surface rust, so I did some preventive maintenance:

Not sure, but it looks like the frame fits all models, maybe even petrol/diesel. New one P/N 31406808 is pricey at 1300-1800 EUR.

The bracket P/N 31368100 underneath the radiator is less than 50 EUR.

Yours looks bad. I'd go after a good used one and refurbish it the best I could before installation. Used ones start at 150-250 EUR and don't look bad on the pictures. Esp compared to yours...

Yeah quotes for new were insane here. But yes, a lot of road salt over the winter here. Never seen so many rusty cars! Mines is ok, just that subframe has taken a beating.

Agree with Graham.

Funnily enough I asked Canadian Tire here to do an underbody corrosion spray... as well as peeing in the wind! **** poor job they did, infact did they even?

Doesn't look like they did a great job. In fact, I can't really see any evidence of any treatment!

If you do get a new subframe, make sure you get the car properly treated underneath. You'll end up in the same predicament in future if you don't. I know its not your fault, but they really did do a **** job.

Sadly, its not going to be a cheap fix. I don't know how long you plan on keeping the car? A new sub frame, plus fitting and getting it undersealed professionally with a decent product like fluid film would cost you around $3,000+

I don't think you'll have much luck finding a second hand subframe in decent condition. Salt eats cars alive over there! Its worth a try, but I'd be doubtful.

Only here for say another 18 months before coming back to the UK, so I am inclined to leave as is. Spent money getting the PCV replaced and other bits and pieces... Got a hole in the exhaust and rear trailing arms need doing also... The exhaust Ill get a muffler repair guy to sort it as Volvo here were wanting $7000 for a whole new exhaust system!

Apart from the above, the car runs great. Had it for almost 6 months now.

Fair enough. Its not worth spending that money if its not being kept long term.
