Today my Jackie is in having its front rubber boots done. The front left had collapsed in without perforation / tear and the front right had a small indentation which had caused a small hole. The 4wd shop says they have come across this.
Does anybody know how it happens ???? 85000 km, 1999 Jack , so manual locking hubs.

PAULL,

This is a normal wear'n'tear issue with this model Jackaroo. (I have same one)

My most recent 70,000K service at Holden Dealer resulted in a report that "The boots had gone into vacuum. Not a major issue apparently, but needs monitoring.

Sounds like the boot has some sort of pressurizing to help keep out dust, etc.

2000 with 83000kms on it. I looked at the boots on sunday morning, they still look good as new.

I'm aware of one Isuzu Trooper owner who Armoralls his under vehicle rubber fittings once every 3 months. Might sound pedantic, but then again it may extend the life of the rubber.

Ya mine have 'sucked' in a bit as well, but no holes or problems --yet------( fingers crossed) Might have to get under for a fiddle and fix it. Front uni is a bit loose so i probably should go the full re-build of all unis and cv's. Mine is 98 jack 130k manual hubs.

My front right had sucked in, when my mechanic looked at it he said it had a small tear. Replaced the boot, now on hard lock 4wding it clicks. I think my cv is going.

Just a thought if it is sucked in, wouldn't it be sucking in dust as well.

Cheers

Paull,
According to Isuzu this is a normal occurance.

I don't think they are 100% sure but they reckon it is
the air in the boot expanding when the CV heats up (in use)
and expels past the boot tie-straps.
Then when everything cools down air cannot be drawn into boot again.

I guess with the extra flexing from the boots not holding shape, a split
could occur prematurely.

However I haven't heard this happen on other makes with IFS. Strange?

Cheers

Thanks for all replies, the front left had really sucked in till it was wrapping around and touching the CV, the front right not so far inb but it did have a tiny hole in it, so I replaced both boots. The grease inside looked pristine, and luckily I haven't been off road for a while . So I think the CV joints are ok. Does this problem recur now ?????
