1998 V70R swap complete with issues

Very nice!

For secondary air injection faults you can just get rid of the system by either installing a very cheap diode (PM abscate he can send you one) or reprogramming the ECU. If you go the diode route there are a few things to pay attention to as far as what needs to be left in the engine bay but it's very straightforward.

Update: Cruise was just missing the vacuum line being hooked up and works just fine now. I cleared the codes using the 850 phone app and I don't know how, but that seems to have solved the right rear ABS sensor issue. Now I'm just down to the prop shaft, EVAP, and SAS delete. I think that I'm just going to try and find an older viscous coupling so that I'm not making a custom prop shaft. The one that I have is the serviceable kind and is in good shape.

I have read the thread again. So if I understand this correctly, you have swapped the mechanics from a 98 V70R and transplanted them into ?? You say it is a 2.4 LPT AWD. Is it a V/S70 AWD with the LPT motor and a 98 model also?

If that is the case, then I would have expected the propshaft to swap over too. I believed the 98 AWD and R used all the same driveline with the exception of the motor. If that is the case, the viscous couplings should be the same as well as the propshaft?

Volvo did screw around with that stuff in late? 98 and it changed again around 99-00 so there are 3 propshaft variants that I know of.

As mentioned up thread , pm me your snail mail address and I can send diodes for the SASdelete.

I even ship to Canada

It is a 98 V70 2.4 LPT AWD that I have swapped the engine, trans, angle gear, and computers from a 98 V70R into.

So here's where things get freaky even for those of us that know that Volvo got weird with the parts. My car was made in 01/98. It had the mechanical timing belt tensioner and a smaller size plunger joint on the angle gear and viscous coupling but the longer prop shaft. The donor car was built before mine and has the hydraulic timing tensioner, larger plunger joint, and shorter prop shaft. According to car-part.com, there was a VIN range change that makes a difference on the prop shaft. So, those built thru VIN 465398, they had the longer VC, larger joints, and shorter shaft. Those with VIN from 465399 got the smaller joints, shorter VC, and longer shaft. I knew that they made changes in 99 and 00, but I didn't know that they had made a change between those built in 97 and 98.

Abscate, check your PM's

Is what you call a plunger joint the flange joint on the output shaft on the angle gear to the prop-shaft? The diameter of the flange does change. The difference in length was caused by the different type of flange. The earlier one had an almost flat faced flange and the later ones had a cupped flange.

So is the problem you don't have the correct flanges to make your prop-shaft work or do you not have the VC and prop-shaft from the 'R'. As far as I know the V/S70 was not sold in North America until the 98 model year which starts in fall 97. I had a 98 registered V70XC which had the hydraulic tensioner and small diameter flat prop-shaft.

The only earlier AWD was the 850 AWD but it was not sold in the US only Canada and had a manual transmission.

So what parts do you actually need to complete the car? Can you swap the flanges, but then if you had them then I guess you could just swap the whole units over.

Got your pm

Diodes are free to anyone with “ big “ or “ sky” in their state nickname

You have to grit your teeth, close your eyes, and a take a horrible risk of sending your address to some random wierd guy on the internet. I tape two diodes to an index card and USPS them to you

You rave about how awesome mVS is. Attractive people flock to your door wanting relationships with you, children talk about you in History class, your parents beam with pride, and the World applauds your success as it’s own.

Plus with two diodes you get another try if you cook the first one while soldering.

I spoke with a drive shaft guy about getting the two shafts made into one that works for what I need and he called them plunger style joints. That's where I get the term from. Both of the flanges are cupped. But the one on the angle gear is a larger diameter than the one that came with the car. So what I'm needing is a really early long VC with a cupped flange. I will try to get under the car as soon as possible for pictures for comparison. Or I suppose I could just compare the shaft joints and lengths. I have the VIN of the donor car if someone knows how to extrapolate the build date from it.

There are plenty links on the web for decoding Volvo Vin numbers. I have 2 later style VC units which take the cupped prop shaft. The cupped shaft flanges are the later style. The flat are the early ones.

When we have prop-shaft issues the go to is Colorado Drive shaft. They may be able to help
