I've a rumble coming from the near side front. It's not wheel bearings or wheels out of balance. I've also noticed end float in the drive shaft coming out of the gearbox. Could this be it?
Gearbox was replaced two years ago.
Been in the trade for many many years. Its def not a wheel bearing. I've checked that also.
However, this seems to come from the driveshaft or Gearbox! Hoping it's not the gearbox. It was replaced 2 years ago under warrenty. Oil looks good, rumble is bad enough to feel through the floor and stearing. Starts at 40mph through to about 70mph. Wondering if it's a drive shaft joint. Trouble is, it's an expensive gamble. Rather pin point than chuck parts at it.
Tyres are in grewat condition, wheels are balanced. Edited by: LOZ
Hi LOZ, sorry you did not mention your mechanical ability, hence the answer I gave you. When you mention that the rumble begins at 40 mph to about 70mph- I take it that the wheel has been balanced and that all joints on the N/S are top notch, then, remove the driveshaft from the hub and check the c/v joints, and shaft, if they're ok,,, then you can definately identify the n/s diff output.
It all seems Unique KIA Sedonaproblems that's why i ask all the questions. Is the Diff output a repairable item? I say this because although the car is like new (really mean that it's mint inside and out) it is very very high mileage all be it motorway miles. It's serviced every 10k all filters, Gearbox oil changed every 30k. Found out today, it does have a gearbox filter but KIA do not change it when they do an autotrans oil change!! Filter costs £18 inc VAT New gearbox £4k plus ! were is the logic in that?
Also SPIII Auto trans oil is £12 a litre GULP! i'm told i need at least 10 Litres. I know it's still cheaper than a G/box though. Wondering if there is an alternative oil.
I'm afraid I shy away from automatic gearbox repairs, I think they should be left to the specialists. Drive train noise travels all over the place (as you know) how is the o/s driveshaft support bearing? Splitting up an auto gearbox is something, but rebuilding with the correct tolerences is another. The oil filter cleans the oil for the valves rather than the bearings. There are a few threads on here regarding which oil members prefer touse. My instincts would steer me towards specialists auto box reconditioners, at least you get 12 months warranty.
Hi Loz, Sorry to hear you have problems - with the vibration coming in at certain speeds it sounds like a balance problem of some sort. Is there a vibration damper on the driveshaft - usually a couple of weights clamped either side of the shaft - just wondering if that has come loose and moved slightly - that's if there is one - can't get access to mine today to have a look if there is one on mine. If the shafts bearings gone you usually get a noise, clicking, when turning sharply into corners at slow speeds.Good luck with it, Alan
Everything looks normal. Oil level reads ok HOWEVER and its a big however, Reading a technical bulletin on http://www.kiatechinfo.com/regarding Auto trans (yes i know it's an American site, bulletin alsocovers diesel box) The fluid can get air locks and foam causing it to play up as if out of fluid even though it reads ok.
Auto trans fluid sold by KIA UKis £10(ish) + VAT per litre and for a full drain you need 10.7Ltrs Spec is SPIII so after doing a seach on tinterweb, Carlube do it (ATF U) £26 inc VAT for 4.55Ltrs
KIA UK say Auto box oil change every 30,000 milesthe rest of the world say 15,000 !! WHY??
KIA also remove oil cooler pipes and start enging in N to drain for 30-60 seconds. Sounds a right bodge. No wonder they are pants these gearbox's
ANY HOO, Gearbox oil change this friday. I'm doing it using the (TAKE NOTE KIA UK) "Drain plug"
Will report back.
OH by the way, click link, worth registering, Although it's for US spec, some stuff applies. Interesting reads on ALL the common faults everyone has!
Well after going into town to a store that said "Yes sir, we have the ATF you need" was rather peed off when they didn't. Then comes the standard reply after you say, But the man on the phone said you had it. "Don't know why he told you that Sir"
Took LESS than 24 hours to arrive. Fantastic service. Well recommended. AND half the price of KIA! Just goes to show (as i've always done) bit of research saves you money.
Worth to note. Although KIA Oils would say KIA on them, they also come up with there own product names to throw you off looking elsewhere. Same goes for all car manafacutres. If we take it all literally, SHELL, BP etcMake Coffee and Chocolate bars!!
I still love the old bird even though it drives me potty some days.
Auto trans oil change done, drive great. Only question, ALL KIA data says 10.7 litres of oil required, we did a FULL drain to KIA spec following it the the letter. 10.7 litres of trans fluid puts it half way up the dipstick !! When we Drained the box firstabout 6 litres came out. So who's right? KIA or dipstick? Have heard of vehicles having incorrect marked dipsticks in the past, The marking on a Sedona seem at the very tip of it and not far apart. All that said, i pulled away at the traffic lights and lite up the front tyres !! never done that before, actually it's never driven so well.........EVER !! Edited by: LOZ
Having read reams of data on these gearbox's with TCM updates etc, wondering if most problems are because
1. Not enough fluid from new ( i know there is a recall certain modelsof Land RoverDiscoverys because of wrong length dipsticks)
2. Initial gearbox probs are due to brakes on N/S/F binding putting strain on the box i.e. box wants to drive, brakes won't let it
ALSO, brakes binding generate heat. Is the heat transfer speeding up the melting point of the grease in the Outer CV joint?
