Volvo Repair Database DIY: 1998 V70 Axle CV Rubber Boots Tips/Tricks

Post by cn90 » Wed May 19, 2010 7:34 pm

This is nothing new in this forum but I want to share some tips on FWD CV Joint Boot Replacement to make it painless for you guys. Of course you can always buy rebuilt axles, which are easier to install.

However, if all you have is torn rubber boot (axle CV joints still OK), then you should re-use the OEM axle as it lasts 200K if well-cared for. Also, it is made for Volvo by "GKN/LÖBRO", which is a very reputable company.

I bought the CV Boot Kit from eeuroparts for $29. The Volvo OEM Rubber Boot is $60, and is a bit thicker than Rein ($29). Anyway this is the one made by "Rein":
http://www.eeuroparts.com/Main/PartDeta ... ?id=271648
(Made in Germany with 3 bags of grease, 90 grams each, so 90 grams x 3 = 270 grams, enough for one side).

Read these nice write-ups by Mr. Winkey and Bay 13:
http://volvospeed.com/Repair/cv_boot.html
http://volvospeed.com/vs_forum/index.ph ... -boot-kit/

These are my tips in addition to the above write-ups:

1. Go to Home Depot or any hardware store and buy a 4-foot section of 1-inch galvanized piping (for natural gas): $13.00. You need this to remove and install the 36-mm axle nut.

2. The 36-mm Nut that holds the Axle: A 1/2-inch breaker bar is good enough (no need for 3/4-inch breaker bar), but when using the galvanized pipe, insert the 1-inch galvanized pipe all the way down the shaft of the breaker bar so it does not bend the breaker bar.

3. It is better to remove the Brake Caliper and tie it to the Spring as in the write-up, as this allows more movement of the Hub. However, if you decide NOT to remove the Brake Caliper then: For L side Axle, turn the steering to the R side and vice versa. This is because the Brake Caliper sits in the front of the rotor. By turning the wheel to the opposite side, it releases the strain on the brake rubber hose.

4. Remove ABS Sensor on top of the Hub: 10-mm socket.

5. When disconnecting the Control Arm’s Lower Ball Joint, use a rag to PROTECT the its rubber boot to prevent damage from all the maneuvers!

6. To replace the Rubber Boot, it is MUCH EASIER to remove the INNER CV Joint than the OUTER Joint. It took me one hour playing with the OUTER Joint Circlip and tapping it to no avail!!! However, the INNER Joint is much easier:
- Using liquid paper, mark the locations on the axle so when re-installing, they align to the same spot.
- Remove the INNER Joint (see write-up by Mr. Winkey)
- Clamp the CV Shaft on a Vice:

- Remove the INNER Joint's circlip (Figure 02):
- Using a drift, tap the INNER joint as shown, it will come out in 1 minute! (Figure 02)
Volvo-CVJoint02.jpg
- Once the Inner Joint comes out, Install the OUTER Boot first (apply grease on the small lip of the boot before installing, it makes it much easier to slide the rubber boot in, also grease prevents damage to rubber during installation!); then install the INNER Boot, also using grease.

7. INNER CV Joint:
* 120 grams of grease (Per Haynes Manual); but I used 160 grams.
* Larger clamps

8. OUTER CV Joint:
* 80 grams of grease (Per Haynes Manual); but I used 110 grams.
* Smaller clamps
Volvo-CVJoint03.jpg
9. The 36-mm Nut: Tighten it to 120 Nm torque, then turn another 60 degrees.
To make this easy: After you have achieved the 120 Nm torque, using a black marker, mark the 36-mm nut @ 12 o’clock position, then turn the Nut until the black mark points to 2 o’clock position.

10. Optional: Align the car.

Thanks cn90! As usual, added to the repair database :wink:

I will add, though, that while this is great if you catch it early on, if your CV boots have been cracked for some time, it is a better idea to just replace the axle, because often times dirt and other crud has gotten through the boot into the CV joints themselves. If you're noticing a clacking while turning, your CV joints are shot.

If you have the correct circleclip pliers ( they look like an L shape where they engage the clip) the clip disengages fairly easly. It still will take a few tries to get the joint off.

I'm wondering about CV Axle repairs too. The '98 S70 I recently bought's boots are completely split all the way around...my friend said he noticed dirt, 'debris', in there.

If I go the replace the axle(s) route, instead of just the boots, do I have to replace both sides at the same time. Or can I replace the left side axle first, and replace the right side axle later? A few months later maybe?

Thanks guys,
Peace.

If there is no clunking sound during turns, then your CV axle ball joint is still good.
- Just clean the inside of the CV joint (get plenty of used T-shirt then wipe all the old grease out).
- Then soak the joints in gasoline to clean all the old gunk, dirt out.
- Dry it
- Then apply new grease (supplied with the CV boot kit).

Update,

After 3 years and 22K miles, the OUTER CV Boot from Rein starts to crack, some grease start to seep out, so I am planning to redo this soon. So much for "Rein, Made in Germany" CV Boots that I was proud to install back in Oct 2008!

This time Volvo OEM Boots or GKN-Lobro Boots only.

So, I was at the local Volvo Dealer, and for 1993-1998 850/S70/V70, Automatic and Non-Turbo:

- COMPLETE BOOT KIT: incl. INNER and OUTER Boots.....PN 271648.....approx $70 online Volvo sellers.

- OUTER CV BOOT.....PN 31256235.....approx $60 online Volvo sellers.

- INNER CV BOOT.....PN 31256225.....approx $32 online Volvo sellers.


Anyway, I am staying away from "Rein" and "EMPI" CV Boots.

I will try to source GKN-Lobro CV Boot, the problem is: While the OUTER CV Boot is easy to find, the INNER CV Boot is not sold by places like autohausaz, rmeuropean, eeuroparst etc.

I saw this video but did not attempt to do it.
As far as your cir-clip. I replaced two boots on my car and each time had the same problem, I could not remove it . I ended up going to shop where they helped me for $10. First time I did not see how they did it but second time I saw it. I could not believe how easy it was. What you need is air hammer ($10-15 in Harbor F). You put the axle in the vise, outer joint toward the ground, one hand spreading cir-clip, second hand is holding the hammer that delivers few knocks and it's done. Next time I will be doing similar job I am buying air hammer.
I got LOBRO kit for $20 something from FCP Groton. First they sent me EMPI kit (boot was nice but cir-clip was just wire wrapped around some body's finger) but I wanted LOBRO since I had installed one already on passenger side.

Update, I ordered the boots and will replace them this weekend with updated pics.

1- INNER Boot: EMPI. As it turned out EMPI is an American Co. servicing mostly VW/Audi over the years, then they started making CV Boots for many cars etc. The CV is made from Neoprene.
EMPI Inner Boot $12.
Volvo OEM Inner Boot $40 (GKN does not sell this separately)
Therefore I went with EMPI Inner Boot as the Inner Boot is rarely an issue.
Usually the Outer Boot fails first (turning R and L creates cracks in the boot over time).

2- OUTER Boot: I will use GKN, because this is OEM and when I last changed the boot in 2008, I know the OEM lasted 10yr/90K.

- Re procedure: you don't need an air hammer. A drift + hammer is good enough.
Very often you don't have a 2nd person to help, and I don't have 3 hands (one to spread the circlip, one to hold the drift and one for the hammer LOL!).
So I am thinking:
1. Mount of a Vise.
2. A Drywall screw (of whatever screw) to spread the circlip apart
3. A Drift
4. A Hammer

I will post an update this weekend.

I used this type of boot since I did not want to attempt taking the axle out. I had a hard time on my previous car so I was prepared to use this method once I noticed the boot was ripped.

I order my kit from a place in toronto called millenium boots or something. It was extremely easy!
