fron't cv boots dry rot 18 months after being replaced?

[omodos]

Both sides show the same wear cracking, reckon I am on borrowed time? noticed though that this time since last change out where i sprayed silicon spray on both sides, and for and as per imageo, splits/cracks seems only isolated as per pic on the ends, whereas past failures have always been between the belows of the boots...anyone spray their boots too?

It looks like the boot was not installed properly in the first place or did you try reclamping the big end??

Hello again, both sides have perished at that location, done by different dates by different mechanics.....pic maybe slightly misleading as yes seems that the boot is ready to slip off ie. clip half way on and off, but clamp goes round boot end so to speak and doesn't ovelap as seems in pic...ok maybe one mechanic doing a kaka job I understand, but the one who did the boot in pic was the one that flawlessly changed out my cracked exhaust manifold too...so not sure...hmmm

The GKN boot usually gives you 12-15yr and 140K miles service life.

The Front CV boots in my 2006 X5 with 143K miles are still
factory original. But I will have to replace the boots soon.

Ok thanks for the reply, means I got something wrong going on up front, car has 105,000 miles on it, and this is the 3rd time that front boots are being replaced....not sure of brands but in one instance it was a gkn boot on one side...am pretty sure though that this wear is partly caused by temp and weather conditions, EVERYTHING that is plastic just disintigrates in the sun here and whilst the boots don't get any sun the radiant heat from the super hot tarmac am sure dries em....

It's not the climate, where I am is usually 52c-55c although it has hit 60c.

I would say that the boots are being installed "just" good enough and in a hurry OR the stock is so old, poorly stored, etc that a ton of life is gone.

I suggest that you do the next set yourself or buy good boots (mark them) and take them to your mechanic and see if they are the same ones installed afterwards.

Hi thanks, interesting you maybe right just wondering how wrong installing these can go?, you can't really put boots on too far over the cv joint at one end or too far down the shaft at the smaller end of the bellow i recall there are grooves to guide you, resellers out here mostly stock the febi and the gkn ones, i'll call up and find out....but yes you maybe right if the items don't have date stamps I wont know though they are fresh although not too sure how fresh a part can be for a nearly 20 year old car....does cv boot replace procedure cause any changes that will make necessary steering re-alignment you think?

PS I have had them done by 3 different mechanics so far....

Why is it so difficult to justify original BMW parts after these experiences?

Hi Clavurion, yes you maybe right but on the matter of shelf life if this specific type of cv boot is only compatible to a specific make year model of bmw that has gone out of production a while back, are the parts supplied for it 'old' stock, I mean is lemfhorder or whoever still churning out these boots?

I renewed the front drive shaft boots as a preventative maintenance 6 years and 150 tkm ago with original BMW parts. No problems with them so far.
