CV joint and new rubber boot or just the rubber boot

[bmbmdmb]

I called dealer to price up CV boot kit.

Used part number off old boot. 

Apparently, Skoda no longer make CV boots for the Fabia. You need to go aftermarket. Obsolete part.

 

Priced up some 6speed gear oil in case garage decides to take off whole driveshaft. Previously, I changed it. £45 per litre (Fabia vrs takes 2l). Pricey stuff. 

 

Picked up outer CV joint kit from ECP.

Despite photo, customer service online and a tel call to local shop all stating hub nut present, this was not the case. £10 separate item. No problem , but I now have to go back when not passing. 

 

Otherwise has all bits

Laser CV joint puller is 11.5cm width rather than 9.8cm.

It would work.

£85

 

6th gear helped but driveshaft still turned when torqued up tool. 

 

Front wheels turn in unison. Does front differential work on when engine on and power applied? Ie front wheels turn independently.

They never did make them, just like they dont make the majority of the parts that are delivered to their assembly lines by OE manufacturers.

 

They no longer stock the CV boots and other such parts that they never made in the first place, as they are a consumable item there will be no end of aftermarket offerings, for something more specialised say a gear selector cable they have to stock the items for I think something like 8 or 10 years from last year of vehicle production but for consumables in abundant supply they would not have to, a silly example would be that no vehicle manufacturer holds stocks of tyres amongst the parts department supply chain (unless specialised) nor would they have ever made the original fitment tyres.

My puller cleared the CV Balljoint with the clamp properly adjusted but it was close, if it is binding then yes you will break the tool or strip the threadso ensure you have it adjusted properly. Good Luck, now is the season not to be working outside on cars.

I measured 9.8cm and the tool states 9.8cm clearance. I had to hammer tool in place. It needs the bigger CV puller I wasn't aware of. The driveshaft really needs to come off and garage are doing exactly this. The driveshaft just spun with little torque. Really needs clamping in a vice.

 

Apparently, the inner driveshaft gets marked with gearbox before removal and this is important to ensure driveshaft is 'balanced'. Not sure about this. If I could of used the tool in situ this would have been a job for me. 

 

I have my garage but even under cover yes it is cold!

I didn't have much choice as the CV boot had a cut in it and leaking. Didn't want to risk rain, salt , dirt getting in.

Final update

 

As driveshaft coming off I thought I'd get the inner CV boot replaced. ECP image was incorrect for the GKN product. It came with one crimp (large end), metal plate flange with the 6 driveshaft bolt holes, wrong sized hub nut, circlip, grease. 

Apparently, no crimp needed for smaller end of boot (approx 3cm driveshaft diameter end) 

 

Amazon sell a febi hub nut for under £7 if I'd known. ECP ordered me hub nut and when I arrived I was greeted with a wheel nut!

Ok, I had another go this pm. 

Watching both videos I posted above involving CV joint puller I realised the problem. My outer CV joint metal cup is too wide for the puller. The two metal prongs touch the CV joint jamming it.

See photo

 

 

The end of the puller goes over the hub nut threads but then is a few cm from touching the CV joint over the threads that engage the wheel bearing - gap between my thumb and index finger.

 

See photo

 

Tightening the 12 point 35mm hub nut only serves to squeeze apart the two puller prongs. I took the clamp out btw of the puller. Reversing the tool, the hole at end is wider than the threads so this not the issue. 

 

I only seen this tool and those for use on trucks. Surely a Fabia doesn't have the largest CV joint of all cars? 

Distance between prongs of puller is 9.8cm

 

I put driveshaft back on hub and ball joint back on. Probably going to take to garage 1/4 mile away and bag CV joint and tape ends to protect.

 

Seems to be one of those jobs which is seldom done and needs pricier tools.

 

I had to hammer prongs to position. Risks damage to threads when tightening if offset.

 

It might be me, but it looks like more faffing with that puller than it would be spend another 5 minutes to just take the driveshaft out completely, put it in a vice and give it a good hit with a hammer.

I took it to garage for £45. 

I don't have a vice, so it would have meant me going to parents and use theirs, then either use the hammer or the larger CV joint puller. 

 

Got the inner CV boot changed as this one has more angle / Flexi due to driveshaft being shorter on front left and I noticed it often splits. For £12 saves fath in a few years when it would have gone.

 

Apparently, the gearbox doesn't leak oil when driveshaft taken off on this model.

 

Garage did say the plastic specific fit outer CV boot was a pain to fit (that is all I could buy, although they said universal rubber might be better). I had to take it back down as the smaller crimp over driveshaft 3cm diameter was wandering over driveshafts between the two boots! 

 

There is a notch/depression in the driveshaft for it to seat.

 I have fitted a couple of OEM ones before and they are incredibly rigid and thick, probably a reason why they last a long time
 

That said I have used my fair share of stretchy ones off eBay as well and never had any issues.

Resurfaced topic... unfortunately!

 

Sometime in September I noticed the outer CV joint had lost its small clip. It was there for the wheel bearing change during summer.

 

Garage that fitted only warrants work 3months. The proper clips were ordered in. Because a mechanic had left they was a 1 month backlog of appointments.

 

I removed driveshaft and cleaned out CV boot and regreased, removed water. TPS small CV boot clip was no good for ECP CV boot (remember dealer could no longer supply the CV boot, obsolete). 

I bought some Amazon CV joint clips and they were decent, tight fit. OEM one was too small by 4mm.

 

The OEM clips just would not compress enough around the boot and driveshaft to engage the ears in the holes in the clip. I don't mind the CV moly grease mess but those clips are razor sharp if you slip and this is the nightmare part of the job.

 

I checked each day and then weekly and after a 3 month the boot is leaking grease from end despite the  small clip being in place and being rock solid. 

 

I'm not loosing much grease and previously used a smear of RTV on the end of boot, just in case.

 

Tonight there was still some grease leaking, a smear from the end of the boot.

 

MOT fail I understand?

 

What are my options? 

 

- new driveshaft? Fit myself. I checked ECP and CP4L and they don't stock. Online gives £80 driveshafts that are of maybe dubious quality.

- remove small clip and try refitting a new one. I got the clip in the groove. The one on now looks well seated. Don't know what I'll achieve.

- take back to the garage and hope they can refit better than me and have an imaginary tool that hold CV joint clip around the boot very tight before using pincher CV joint clip tool to tighten.

- Original mechanic suggested fitting flexible rubber CV boot. Some had mixed reviews on quality on this.

 

MOT looming in March.

 

Thanks

Just clean it up before going for MOT, no need to make a mountain out of a molehill. You may just have overfilled the joint with grease, also you need a special tool for OE clips which is expensive to buy.
