  • CV boots splitting due to suspension lift ?

    Hi guys, my inner cv boots have split since having my suspension upgraded. I know this is a common problem with hilux's after being raised as my mate goes through a couple of sets a year and he is the one who pointed out that mine were split. I'm wondering if anyone else has had this problem and has it re-occurred after being fixed ? or does any one have any tips to prevent it happening again once repaired ? Is this a common problem with prado 90's ? or have i just been unlucky ?

    Cheers,
    Alan

    Re: CV boots splitting due to suspension lift ?

    if you have an earlier model prado, it's just possible that with any rubber it dries out and small cracks appear,
    from movement and flex.
    then lift the vehicle and the cv is put in a flexed position and those small cracks get worse the more you flex
    until the small crack makes it right through.
    i don't believe it is 'common' on prado's.
    in my time on the floor, the different quality of cv boots does vary alot.
    i my experience, the toyota boots seem to be thicker and therefore tougher,
    and aftermarket (non-genuine) boots (varies with different brands) seem to be thinner and therefore can flex alot easier.
    the adventage of the thinner boot is the easier the install, and allows the shaft to flex easier when attached to vehicle.
    the disadvantage is it takes less to damage the boot.
    my opinion is stick with genuine if your paying someone else to do the job, as the boots will last longer (thicker),
    or if your doing it yourself either option;
    cheap job go non-genuine or moderate cost with genuine but should last longer.

    a tip to keeping the boots in good condition is to spray them with something like almour-all fortnightly.
    this will keep the boots in good flexible condition and reduce those little cracks from starting and growing.

      Hi Alan,

      It could be to do with the amount of lift you received. I've heard around 40-50mm lift is OK but over that and CV boots can start to suffer.

        Thanks for your reply's fellas. My mates hilux seems to chew through them and was hoping it wasn't a common prob with the prado as it is an expensive exercise every time my mate has them replaced, the last lot he put on only lasted a week and he hadn't even taken it offroad.
        I'll take your advice damonat and i'll get the genuine boots put on when i have it repaired.
        Snaga - i only got about 40-50 mm lift (EFS), not sure of the before measurements but after the lift it measures around 780 mm on both sides.

          Seems about right... when mine were first done the sat at 770mm and now (a few months ago after 35000klm's) they're at 760mm.

            Re: CV boots splitting due to suspension lift ?

            I got a price today for a set of genuine Toyota cv boots, the inner boots are $140 per side and the outer boots are $80 per side. I only need the inner boots replaced on both sides but i thought it would be best to do the lot while i'm at it . I can't believe how expensive they are for the Prado, it cost less than $100 for all 4 genuine Toyota cv boots for my mates 99 Hilux. Its going to be a bit of an expensive exercise replacing them as after paying a bit over $400 for the parts it will cost me another $300-$350 to have them fitted. I hope this isn't going to be a recurring problem.

              Gday Pythonkeeper,

              Might be worth checking these out on the locktup4x4 site, theres a fair bit of good 90s gear on there: http://www.locktup4x4.com.au/product/a2 ... e49bb.aspx

              I havn't used them but they look suitable, cheaper than toyota and designed for lifted applications.

              Cheers,

                  I booked the beast in for next Tuesday to have all 4 cv boots replaced. She's getting done at Opposite Lock Redcliffe they are supplying and fitting all 4 boots for $250, i'm allot happier with that price than paying $450 just for the parts from Toyota.

                    Forgot to update this thread after the repair. Well it wasn't split boots after all. It ended up being a combination of increased angle and to much grease packed inside the boots which was causing the leak on both sides. So to fix the problem the mechanic removed some of the excess grease and put some new clips on and it's been fine ever since. Ended up costing $25 instead of $250, sweet.

                      Good to hear mate. I've replaced an inner boot on mine and it wasn't to hard to do, just very messy. Its not often you drive away with work costing less then expected.

                        Cool, that's the exact problem I am experiencing. I installed a lift kit on the weekend and since then one of my inner boots has been spewing grease everywhere, and it's coming from the end. I have it booked in tomorrow to replace the clip. Thanks for the tip

                          Mate if its just the clip, cut it off with side cutters and replace it with a suitable width zip tie. Thats all thats holding mine on since I replaced the boots near 12mths ago, and I haven't had any problems with regular off road trips.

                            Had an exchange shaft complete with new CV's & boots fitted to my vehicle (passenger side) in April as it worked out to be slightly cheaper than to have genuine boots only fitted.

                            Have done not quite 6000 k's & my mechanic has just confirmed the inner boot has split again, same as the first time. Driver's side boots are OK. The suspension lift was done August '07 & I've done nearly 29000 k's since.

                            I was a bit dubious about having aftermarket boots on the exchange shaft at the time; but was assured they would be OK. Seems like my expectations have been realised :x Now waiting for my mechanic to get back to me with the next step....... :roll:

                              Are your boots splitting or wearing? I had more than the normal 2 inch lift in mine and found that the boots were actually rubbing on themselves as they rotated. If you look at the attached photo you can see the were it has been rubbing on the inside of the outer boot.


                              I have since fitted King springs which has dropped everything back to a more normal level (the above picture really doesnt show how close to level the CVs are now) and the boots no longer rub on themselves. However the damage has been done and I am expecting them to split again at some stage.

                              I also had problems with the CV actually coming adrift inside the diff housing. At times I could actually see close to 2 inches of the shaft outside the diff (passenger side) as the clip holding everything in place had given way (yet again). My mechanic suspected it was due to the droop caused by the lift, hence the change over to King spings. Time will tell on that one I guess. See topic below.
