Boro Posted October 31, 2011 Share Posted October 31, 2011 Came across this by accident whilst looking something else up in the workshop manual it said that early rangerovers will need the studs changing to fit alloy wheels, why is this? does anyone know the part number for the correct studs which apparently have a line of triangle on them, thanks Quote Link to comment Share on other sites More sharing options...
bishbosh Posted November 1, 2011 Share Posted November 1, 2011 They are a different length to cope with the thickness of the alloy wheel. Ralph will be along shortly with a part number Quote Link to comment Share on other sites More sharing options...
mmgemini Posted November 1, 2011 Share Posted November 1, 2011 I don't have the part number. Look at your wheel studs. Is there a "V" or a chisel mark on the end. If there is then you have the correct wheel studs for aluminium alloy wheels. When on the subject of wheel studa. Are the TD5 Defender studs longer than the marked one fitted to the Range Rover/ Discovey/ Defender ? Quote Link to comment Share on other sites More sharing options...
Boro Posted November 1, 2011 Author Share Posted November 1, 2011 I did look at them but not surprisingly (being a 71) they dont have the markings so would need changing Quote Link to comment Share on other sites More sharing options...
western Posted November 1, 2011 Share Posted November 1, 2011 the only parts info I have for RRC starts at 1986 -- these use FRC5926 studs for vehicles up to 1991, don't know if these will be usable on a 1971 model. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted November 1, 2011 Share Posted November 1, 2011 How long are the studs from the hub face ? Having had to measure the stud length on my Defender for a project I found the lenght to be just a midges under an inch. The Td5 ones I measured were longer but I don't know why.

Boro Posted November 1, 2011 Author Share Posted November 1, 2011 lr series site turns up these these http://www.lrseries.com/shop/product/listing/6538/RUF000080-WHEEL-STUD.html?search=wheel%20stud&page=1 i will order one next time im ordering from them to try out, not sure how long the studs are i will have a measure at some point and compare the lenght to those on a spare discovery hub i have as i know that has the correct studs, i have ordered a parts book for the early range rover now so with any luck they will be shown in there Quote Link to comment Share on other sites More sharing options...
Boro Posted November 3, 2011 Author Share Posted November 3, 2011 I have measured those on the rangerover (which carry no markings) and they are approx 25mm from the hub face, i have also measured those on an old discovery hub i have (which carry the markings) and they are exactly the same length so i dont really know what to make of it now, the one thing i have yet to do is remove a wheel from the rangerover maybe they arent threaded all the way or something thats all i can think of unless they had a different tensile strength but i cant really see why they would Quote Link to comment Share on other sites More sharing options...
Briarston Posted November 4, 2011 Share Posted November 4, 2011 Eary RRC's had steel wheels (Rostyle comes to mind) which I think are probably thinner than the later alloys, thus extra length needed if up dating. They were the correct standard steel wheels on my 1979 model. No idea of part no.'s through. Quote Link to comment Share on other sites More sharing options...
Boro Posted November 5, 2011 Author Share Posted November 5, 2011 Found the difference, according to the parts catalogue i have just bought for it alloy wheel studs have a larger head Quote Link to comment Share on other sites More sharing options...
mmgemini Posted November 5, 2011 Share Posted November 5, 2011 If you read the Haynes that I have somewhere it explaines the differences in there. The marked ones fitted to my Defender are 25mm long looking at the depth gauge I have they're at tad inder 1". Quote Link to comment Share on other sites More sharing options...
Boro Posted November 5, 2011 Author Share Posted November 5, 2011 Neither the haynes workshop or restoration manuals go into details about the difference just that they are different and to run alloys i need to change to suitable hubs and studs, the parts book actually states the difference as alloy wheel studs as having larger heads, need to do some measuring now and see whether these studs will fit my hubs or whether i need to change hubs as well which i could do without, does anyone know whether the later metric hubs from an 86-94 rangerover will fit the pre 86 imperial axles without the need to change other parts? from what i can see the wheel bearings are the same, not sure about the drive flanges though, discs need changing anyway Quote Link to comment Share on other sites More sharing options...
mmgemini Posted November 5, 2011 Share Posted November 5, 2011 I've given you the lengths for the stud for aluminium alloy wheels. I too use alloy wheels but in this case mine are alloy steel. As long as the end of the stud is marked as per HAYNES manual then you are fine. All wheel/ hub bearings are the same from the sater of the Series Three through to the end of the 300Tdi engined vehicles. That would include the V8's fitted withing those years. Well my copy of Haynes does state the difference. Sorry but I have no idea where my copy is as since we came home in March we've had to do a lot of work in the house so we don't know where things are.

Boro Posted November 5, 2011 Author Share Posted November 5, 2011 As i mentioned earlier although the length of marked studs and mine are exactly the same the studs on my range rover do not have the markings, this was why i was trying to find out what the difference was given the lengths where the same, parts catalogue says different stud head size, next step for me is to see whether the correct studs fit my hubs or whether i need to change hubs as the range rover haynes workshop manual states changing to suitable hubs/studs Quote Link to comment Share on other sites More sharing options...
mmgemini Posted November 5, 2011 Share Posted November 5, 2011 The studs from my 1984 Range Rover which had the three spoke alli wheels fitted are the same as are fitted to my Defender. I canalbalised those studs as spares for my Defender. These studs are tyhe same length as fitted to my Defender and to a Defender I measured in a workshop that had the wheels off. What does your dealer say. He should be able to tell you. Quote Link to comment Share on other sites More sharing options...
Boro Posted November 5, 2011 Author Share Posted November 5, 2011 From what i can see alloys only became an option in 1981 so i guess its around that time landrover modified the hubs, i fancy asking the dealer would be a waste of time for a 71 range rover, everything is computerised now and pre 85 wont be on the system Quote Link to comment Share on other sites More sharing options...

farmerboy_y2k Posted November 5, 2011 Share Posted November 5, 2011 everything is computerised now and pre 85 wont be on the system At home i've got 70-85 and 85-95 genuine computerised parts book on cd, so a dealer should have them as well.
